32.2 g of benzylamine, 14.8 g of 4-bromobutyronitrile and 30 ml of cyclohexane are stirred at room temperature for 12 hours. After the addition of diethyl ether the separated benzylamine hydrobromide is filtered off; the ether phase is washed with water, dried and concentrated by evaporation. The residue is distilled in vacuo to yield 11.5 g (66% of theory) of 4-benzylaminobutyronitrile (B.P. 114° to 120°/0.05 mm Hg).
