Procedure

Stir 4-bromomethyl-benzonitrile (2.0 g, 0.010 mmoles) in sealed vessel in a solution of 2N ammonia in methanol at 80° C. until completion. Reduce solvent in volume. Dissolve residue in ethyl acetate and wash with 1N HCl. Basify aqueous layer with 5N NaOH. Extract aqueous layer into dichloromethane. Dry organic layer over MgSO4 and reduce in volume to isolate 0.223 g. Yield=16.8%. Mass Spectrum (m/e): (M−).
