Lawrence, S. A., Science of Synthesis, (2009) 40, 531.
The Gabriel synthesis of amines involves the reaction of a metal phthalimide, usually potassium phthalimide (72), with an organic halide and subsequent cleavage of the alkyl phthalimide 73 to release a primary amine 74 (Scheme 53; see also Houben–Weyl, Vol. 11/1, pp 79–96).[151–156] Cleavage of the N-alkylated phthalimide can be accomplished by acid- or base-catalyzed hydrolysis or by the Ing–Manske modification, which uses hydrazine hydrate in methanol or ethanol.[153]
