実験手順

A process wherein from m-nitrobenzaldehyde is derived nitrobenzylbromide, which is then reacted with potassium phthalimide to obtain N-(m-nitrobenzyl)-phthalimide which is then subjected to a two-stage reduction to obtain m-aminobenzylamine (yield: Ca. 20%) (N. Kornblum et al., J.Am. Chem. Co., 71, 2137(1949)).
