Procedure: 3,3-dimethylbutanoyl chloride (3.37 g, 3.5 mL, 25 mmol) and triethylamine (2.53 g, 3.5 mL, 25 mmol) were added to a solution of 4-bromo-2-chloro-6-(trifluoromethyl)aniline (5.0 g, 25 mmol) in acetonitrile (30 mL). The reaction mixture was stirred at room temperature for 4 hours. Water was added to the mixture, and the precipitate formed collected to give the title compound as a powder (7.46 g, 100% yield). the precipitate formed collected

Procedure: 3,3-Dimethylbutanoyl chloride (1.08 g, 8.0 mmol) was added to a solution of 4-bromo-2-chloro-6-(trifluoromethyl)aniline (2.0 g, 7.3 mmol) in acetonitrile (10 mL). The reaction mixture was stirred at room temperature overnight. Water was added to the mixture and then extracted with ethyl acetate. The organic layer was dried over sodium sulfate and concentrated. Purification by column chromatography (100% DCM) afforded the title compound as a powder (1.22 g, 65%) over the two steps. extracted with ethyl acetate The organic layer was dried over sodium sulfate concentrated Purification by column chromatography (100% DCM)

Procedure: N-bromosuccinimide (910 mg, 5.1 mmol) was added to a solution of 2-chloro-6-(trifluoromethyl)aniline (1.0 g, 5.1 mmol) in acetonitrile (10 mL) and acetic acid (3 mL) at room temperature. The mixture was stirred at reflux to 18 h. The reaction mixture was then filtered through Celite and concentrated to give the title compound which was used in the next step without further purification. at reflux to 18 h The reaction mixture was then filtered through Celite concentrated
