Procedure

Powdered potassium hydroxide (340 mg, 6 mmol) was added in one portion to a stirred solution of 4-(aminomethyl)benzonitrile (200 mg, 1.5 mmol) in 2-methyl-2-propanol (20 ml) at reflux under nitrogen. The reaction was heated at reflux for 30 minutes and cooled to room temperature. The mixture was concentrated under reduced pressure and the crude product was purified by flash chromatography on silica gel eluting with dichloromethane:methanol:ammonia (95:5:0.5, by volume) to provide the title compound (150 mg) as a white solid.
