A solution of 5-cyclopropyl-2-(4-fluorophenyl)-N-methyl-6-(methylsulfonamido)benzofuran-3-carboxamide (1.00 g, 2.49 mmol), 2-(difluoromethyl)-4-fluoro-1-nitrobenzene (1.13 g, 5.91 mmol) and K2CO3 (0.85 g, 6.15 mmol) in HMPA (6.2 mL) was stirred at 60° C. for 15 h. The reaction mixture was diluted with EtOAc and water. The organic layer was washed with brine, dried (Na2SO4), filtered, evaporated and purified by silica gel chromatography (0-80% EtOAc/hexanes) to afford the title compound (1.45 g, 97%) as a yellow solid. LCMS (m/z, ES+)=574.3 (M+H+).
