Reaction Steps

A solution of N-bromosuccinimide (1.0 g, 5.6 mmol) dissolved in DMF (3 mL) was slowly added to a mixture of 3-amino-4-chlorobenzotrifluoride (1 g, 5 mmol) dissolved in DMF (2 mL) and the reaction mixture was stirred at RT for 20 min, concentrated, and extracted with ethyl acetate/water. The organic layer was dried over sodium sulfate, filtered, concentrated, and purified by flash chromatography (eluted with 100% hexanes) to produce the title intermediate as a reddish colored oil (970 mg, 70% yield). (m/z): [M+H]+ calcd for C7H4BrClF3N, 273.92, 275.92 found 276.2.
