To a mixture of 28% aqueous ammonia (19.3 g, 317 mmol, 4.0 eq) and toluene (30 mL) was dropwise added a 4-chloromethylbenzoyl chloride. (15.0 g, 79.3 mmol)/toluene (30 mL) solution under ice-cooling. The mixture was stirred at room temperature for 1 hr. and under ice-cooling for 1 hr. The crystals were collected by filtration, washed with water (9 mL) and toluene (9 mL), and dried in vacuo at 40° C. to give the title compound (13.36 g, yield 99.3%) as white crystals.
