To a mixture of 4-isopropylbenzoic acid (191 mg, 1.16 mmol) and pyridine (0.12 mL, 1.5 mmol) in toluene (10 mL) was added thionyl chloride (0.11 mL, 1.5 mmol). After heating at 80° C. for 3 h, the reaction mixture was cooled and concentrated in vacuo to give 4-isopropylbenzoyl chloride. A solution of this material (1.16 mmol) in methylene chloride (10 mL) was added to a mixture of 2-amino-N-(4-methoxyphenyl)benzamide (200 mg, 0.83 mmol) and pyridine (0.07 mL, 0.87 mmol) in methylene chloride (15 mL) cooled to 0° C. The reaction mixture was warmed to room temperature and stirred for 1 h. The reaction was partitioned between methylene chloride (25 mL) and 1 N hydrochloric acid (10 mL). The organic layer was dried (magnesium sulfate), filtered, and concentrated in vacuo to give 262 mg (81%) of the title compound as a white solid.
