To a solution of 2-chloroaniline (5.15 g, 40.37 mmol) in dichloromethane (50 mL) was added 2,4-dichlorobenzoyl chloride 1 (8.88 g, 42.39 mmol) and then triethylamine (6.1 mL, 44 mmol). The reaction mixture was stirred overnight at ambient temperature and ethyl acetate (150 mL) was added followed by 1N HCl (50 mL). The organic phase was washed with water and brine, dried, and concentrated under reduced pressure to yield a light yellow solid. 2,4-dichloro-N-(2-chlorophenyl)benzamide 2 was used for the next step without further purification. Yield: 11 g, 90%.
