Reaction Steps

A suspension of 2,4-difluoro-1-nitrobenzene (261 mg, 1.64 mmol) and 5-cyclopropyl-2-(4-fluorophenyl)-N-methyl-6-[(methylsulfonyl)amino]-1-benzofuran-3-carboxamide (600 mg, 1.49 mmol) in dimethoxyethane (0.8 mL) and water (0.2 mL) was treated with potassium carbonate (616.86 mg, 4.47 mmol) and heated to 100° C. for 24 hours. The reaction mixture was concentrated and purified by column chromatography to afford 5-cyclopropyl-6-(N-(3-fluoro-4-nitrophenyl)methylsulfonamido)-2-(4-fluorophenyl)-N-methylbenzofuran-3-carboxamide (230 mg, 0.43 mmol, 29% yield) as a yellow powder. LCMS (m/z, ES+)=542 (M+H+)
