Võrreldes P2NP redutseerimisega alumiiniumamalgaamil, pakub see meetod oluliselt vaiksemat reaktsiooni (reaktsioon ei ole eksotermiline ), paremat saagist (90%) ja väga puhast ainet (ei vaja täiendavat puhastamist).

Lahustada 15 g P2N0 50 ml veevabast atsetoonist.
UwgORLNaqc
Asetage 100 ml ümarpõhjaline kolb magnetilisele segurile, mis on varustatud tagasivoolukondensaatoriga. Lisatakse atsetooni ja 42 g tina(II)kloriiddihüdraati.
WHBjLrv8Vi
Lülitage segamine sisse, oodake, kuni tinakloriid lahustub, ja lisage P2NP lahus atsetoonis.
793sHRQ2fr
Segage 20 minutit, temperatuur tõuseb aeglaselt. Segu temperatuuri langus näitab reaktsiooni lõppu. Pange klaasi 150 ml külma vett ja 4 ml 36%list soolhapet, lisage aeglaselt segule segades. Lahuse värvus muutub
KN9JCcf4B8
Valmistatakse naatriumhüdroksiidi lahus (200 g 200 ml vee kohta), jahutatakse see toatemperatuurini ja lisatakse segule pH>10 (happelises või neutraalses keskkonnas on oksiimi ekstraheerimine võimatu), kohe tekib anorgaaniliste soolade sade.
MjP9Yyl5TN
Ekstraheeritakse 3 x 50 ml annust etüülatsetaati. kuivatatakse veevaba magneesiumsulfaadiga. Asetage 60 ml jäääädikhapet keeduklaasi magnetilise segisti peale ja lisage eelnevalt saadud lahus (oksiim etüülatsetaadis).
4wN1jrbhyV
Lisage segamise ajal 10 g tsingitolmu.
3uF8p6UE2i
Segage 15 minutit.
RtmbHplEDL
Lisage jahutatud naatriumhüdroksiidi lahus (50 g 100 ml vees) pH>10.

HUxwgJCtZS
Filtreeritakse segu. lisatakse 50 ml diklorometaani, eraldatakse orgaaniline kiht ja ekstraheeritakse lisaks 3 korda 20 ml DCM-iga vesikiht.
XLBWS4JoQk
Orgaanilised ekstraktid ühendatakse ja kuivatatakse veevaba magneesiumsulfaadi kohal.

ICr7mUoQXK

Saame 10 g amfetamiini aluse lahuse DCM-is. Lisame 50 ml veevaba atsetooni ja soovitud hapet, et saada vastav sool.

Kuni kogu tinakloriid on lahustunud

Kas teil on 37% soolhapet?

kas ma võin siin kasutada 37% soolhapet, mis on valesti tõlgitud

Kas valmistame siis 200 ml veest ja 200 g naatriumhüdroksiidist lahuse ja lisame selle siia?

Miks te kasutate dcm teiste lahustite asemel?

Dcm is awesome and boils off super low... I'll use the or hexane. Toulene... too high more heat and work

Kui palju soovitud hapet tuleb lõpus lisada?

Valage 10 ml atsetooni 1 ml kontsentreeritud 97% + väävelhappe 10:1 suhtega. Kasutage pipetti või süstalt, et tilgutada lahust aeglaselt, kuni saavutatakse pH 5,5. Kui ülehappestatud, lisage rohkem freebaasi, kui kaugelt ülehappestatud ja muutub vedelaks, siis a/b ja uuesti krülistada.

Kas te teate teisi lahusteid, mida võiks kasutada DCMi asemel?

Võite kasutada mittepolaarset lahustit (eeter, benseen, tolueen)

Olen mõelnud ka touleeni peale, aga ma arvan, et tiheduse vahe on liiga väike, kas pole ?

Tere, tänan teid aruande eest! See on tõesti huvitav. 10g amfoonivaba aluse saagis on 80,4%, üsna hea. Kui palju soola saite?

Meetod on kopeeritud internetist.
Kavatsen seda teha lähitulevikus.
Annan teile teada, kui ma seda teen.

i just did this synthesis successfully ! (i was very astonished, that it works, like described...!)

i used 1,7g P2NP

- created sncl2 sol. from h202 and conc HCL first, until total dissolution, quenched oxidizing agent w. Bisulfite.

- dissolved p2np in acetone / EtoH and brought solutions of sncl2/p2np-solvent together in 250ml RBF

vigourously stirred for 2hrs.

------SKIPPED OXIME ISOLATION !!!!! -----

instead gave antoher dash of conc. HCL in to the whole

and gave finely divided active-C powder a hydrogen absorber in to RM.

then three portions of Zn-dust were introduced in several heaps...with subsequent hcl/EtoH addition.

as the reagents were used up i gave a small am. of AcOH to the whole and let it further react out a 15mins.


- now i slowly alkalized to ph 12 (metal precipitates formed immediate and sank...no hassle in base extraction....did with xylene/pet.ether/naphta mixture (+a small emulsion preventing splash of 2-propanol , every extraction step...)


i pooled organic xtracts, washed them with conc.brine f. rocksalt....)

afterwards the washed org.phases were run trough fine filtering apparatus.

added a 100mls of H20 and then titrated with Hcl until ph 5,5 ~


the acidic solution was equiv. mixed with acetone / ethanol-2propanol

with concentration under stirring with surface vent.

then the pasty residue was further refined...

I OBTAINED almost 1,3g amph-hcl (hygroscopic but useable!)

so that is a fine well thought route to go, THANKS TO ORIGINAL MASTERMIND

* MAJOR ! update:...

I DID ONE MORE "GOD-MOVE" AFTER THIS SURPRISE RESULT:.....


I SUCCEEDED IN MODIFYING THE SYNTHESIS - AND DID A REDUCTIVE AMINATION

WITH REFINED P2P AND METHYLAMMONIUMACETATE (OR KIND OF)

IT YIELDED METHAMPHETAMINE RACEMATE.... VERY UNEXPECTED QUANTITY- QUALITY AS SAME AS THE USUAL NABH4 ROUTE I PREFERRED BEFORE...



IT WENT DOWN FROM Imine formation -[ACIDIFIED VARIANT]...... TO HYDROCHLORIDE OF SLIGHT PINK APPEARANCE OVER NIGHT !

-->AT ROOM TEMPERATURE<----

PLEASE dont be mad at me but i decided to keep specifics for myself**

it is a whole new approach to phenetylamine syntheses in general ....

CREDITS TO THIS COMMUNITY PRO INSTRUCTIONAL P2P PURIFICATION TUTORIALS / I WENT TROUGH THE HASSLE OF THE WHOLE WORKUP TECHNIQUES OF THE BB-gate wisdom ...

THE PHENYLACETONE I DERIVED BY : Fe/H+ --P2NP---> Phenyl-2-Propanone



**(exception 4 you, Patton ..i made a writeup , documenting specs etc. i think you get what these
synthesis-dynamic principles hold in value )
