First, into a 500-mL 3-necked round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed dichloromethane (400 mL), 4-bromo-5-chloro-2-methylaniline (25 g, 113.38 mmol, 1.00 equiv). This was followed by the addition of TFAA (trifluoroacetic anhydride, 27.4 g, 130.46 mmol, 1.15 equiv) dropwise with stirring at 0 C. in a water/ice bath. The resulting solution was allowed to react, with stirring, for an additional 1 h at room temperature. The resulting mixture was concentrated under vacuum. This resulted in 30 g (84%) of N-(4-bromo-5-chloro-2-methylphenyl)-2,2,2-trifluoroacetamide as a white solid. First, a solution of 4-bromo-5-chloro-2-methylaniline (5 g, 22.68 mmol, 1.00 equiv), TFAA (5.5 g, 26.19 mmol, 1.50 equiv) in dichloromethane (50 mL) was placed into a 100-mL round-bottom flask. The resulting solution was stirred for 4 h at room temperature. The resulting mixture was concentrated under vacuum. This resulted in 7.9 g (crude) of N-(4-bromo-5-chloro-2-methylphenyl)-2,2,2-trifluoroacetamide as a brown solid.
