Procedure

Methyl 3-chloro-4-methoxybenzimidate hydrochloride, (19.9 g, 0.084 mole) was added to a solution of ammonia (12 g) in CH3OH (100 ml) cooled to -78° C. The stirred mixture was allowed to warm to room temperature. After 20 hours, the solution was evaporated to dryness under reduced pressure. The solid residue was triturated with Et2O and collected to yield 17.8 g (96%) of 27, m.p. dec. 243°-245° C. A sample triturated with acetone melted at 241°-243° C. dec.
