A solution of sodium nitrite (1.9 g) in water (16 ml) was added dropwise to a suspension of 4-aminophenylacetonitrile (3.6 g) in concentrated hydrochloric acid (37 ml) so that the temperature did not exceed +2° C. The resulting mixture was stirred overnight (room temperature), the yellow solid collected, washed with cold ethanol (20 ml) and ether (50 ml), dried (vacuum) to give the title compound as a yellow solid.
