実験手順

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,
