Reaction Steps

Aniline (930 mg, 10.0 mmol) was added to a solution of DIPEA (1.94 g, 15.0 mmol) and 4-bromo-2-fluoro-1-nitrobenzene (2.2 g, 10.0 mmol) in DMSO (16 mL). The reaction mixture was stirred at 60° C. for 4 h. Upon completion, the mixture was diluted with water (50 mL), and the resulting precipitate collected by filtration, washed with water and dried in vacuo. The crude product was used in next step without further purification. LCMS (m/z): 293.1/294.1 [M+H]+/[M+2H]+
