실험 절차

4-(2-Bromoethoxy)benzonitrile (7.3 g) was reacted with potassium phthalimide (5.98 g) in DMF (35 ml) by heating at 95° C. for 3 hours. The N-[2-(4-cyanophenoxy) ethyl]phthalimide obtained after extractive workup (7.30 g) was suspended in IMS (350 ml) and treated with hydrazine hydrate (6.25 g). The mixture was stirred for 22 hours and filtered. The solid obtained was washed with IMS and the combined filtrate and washings were evaporated to dryness. Water was added to this residue and the mixture basified with 10M sodium hydroxide solution. The mixture was extracted with dichloromethane to give 4-(2-aminoethoxy)benzonitrile as an oil.
