Procedure

A suspension of phthalonitrile (70 g, 0.55 mol) in ethanol (100 ml) and chloroform (200 ml) was warmed and then cooled to 0° C. The reaction mixture was saturated with HCl (g) and then aged at 0° C. for 2 weeks. The resultant precipitate was filtered and washed with chloroform. Dilution of the filtrate with ether produced additional 2-cyano-benzimidic acid ethyl ester hydrochloride.
