Procedure

A solution of N1-(4-methoxybenzoyl)-1,2-benzenediamine (200 mg, 0.826 mmol) and pyridine (0.25 mL) in chloroform (5 mL) was treated with 2-naphthoyl chloride (158 mg, 0.826 mmol). After 20 h, the mixture was poured into a mixture of ethyl acetate and 1 N aqueous hydrochloric acid. The organic layer was washed with water, saturated sodium chloride solution, and dried (potassium carbonate), filtered, and concentrated in vacuo. Recrystallization from hexanes/ethyl acetate yielded 211 mg (65%) of the title compound.
