実験手順

A mixture of 5-cyclopropyl-6-(N-(3-fluoro-4-nitrophenyl)methylsulfonamido)-2-(4-fluorophenyl)-N-methylbenzofuran-3-carboxamide (230 mg, 0.43 mmol) and stannous chloride (291 mg, 1.29 mmol) in ethyl acetate (5 mL) and ethanol (5 mL) was maintained at reflux for 3 hours. The mixture was cooled to room temperature and partitioned between ethyl acetate and water. The organic layer was dried over sodium sulfate, filtered, concentrated to dryness, and purified by column chromatography to afford 6-(N-(4-amino-3-fluorophenyl)methylsulfonamido)-5-cyclopropyl-2-(4-fluorophenyl)-N-methylbenzofuran-3-carboxamide (200 mg, 0.39 mmol, 90% yield) as a yellow powder. LCMS (m/z, ES+)=512 (M+H+)
