Alternatively, recrystallize P2NP again in isopropyl alcohol.
Or continue as is.
Then simply isolate the amphetamine base, extract it. For example, DCM. Distill DCM under vacuum, or simply blow it out with a hair dryer in a WELL-ventilated room. and distill the free base with steam.
And then according to the usual scheme. A-oil + alcohol, acidification to pH 6-5.5

If this happens at the end of the reaction, then everything is fine.

1) the quality of the amalgam (optimally 50 microns of the foil, with a pre-purified surface with a weak alkali solution with compulsory flushing clean water, + 3-5 percent of mercury salt)
2) quality P2NP (melting point, color and other nuances)
3) there is no order and tams of the reaction
