Procedure

A solution of 2-aminobenzonitrile (4.25 g, 36 mmol) in anhydrous diethyl ether (40 ml) at 0° C. is treated under argon with benzylmagnesium chloride (2M in tetrahydrofuran; 50 ml; 100 mmol). The reaction medium is maintained under agitation for 1 hour at ambient temperature, then hydrolyzed at 0° C. by adding hydrochloric acid at 10%, agitated for 1 hour, and neutralized with sodium hydroxide. The resulting mixture is extracted with ethyl acetate. The combined extracts are washed with water and with a saturated solution of sodium chloride, then dried over magnesium sulphate and concentrated to produce 3.5 g of the desired product, in the form of a white solid (m.p.: 100–101° C.).
