The top of the condenser was connected to a sulfuric acid trap and this trap was connected to a gas absorption bottle. The anode is made of magnesium or aluminium, the cathode of nickel, the solvent is DMF g and the supporting electrolyte is tetrabutylammonium fluoroborate 2 g, 6 mmol. PhenylPropanone can be made in a single step by a free-radical reaction between benzene and acetone. The organic phase was dried over MgSO4, filtered with suction, and the solvent removed under vacuum to give a clear yellow oil. The imine salt can also be reduced directly to amphetamine by sodium borohydride in methanol in high yield. During the reduction the surface of lithium became pink.

    Methamphetamine (contracted from N-methylamphetamine) is a potent central nervous system drug, is p-hydroxylated by CYP2D6 to less active p-OH-​methamphetamine. The simplest unsubstituted phenylisopropylamine, 1-​phenylaminopropane, or amphetamine, serves as a common structural template for. para-Chloromethamphetamine is a stimulant that is the N-methyl derivative and prodrug of the neurotoxic drug para-chloroamphetamine (4-CA).

    It has been.
    I think the purity of final product would be higher if reaction mixture was first poured onto ice, then acidified. Neutralize with sat. The combined extracts were washed with water, 1M hydrochloric acid and satd. In this preparation, phenylnitropropene is reduced to phenylnitropropane with NaBH4 in methanol, followed by hydrolysis of the nitro group with hydrogen peroxide and potassium carbonate, a variety of the Nef reaction.
