Procedure

To a solution of 5-cyclopropyl-2-(4-fluorophenyl)-N-methyl-6-(N-(3-(methylsulfonyl)-4-nitrophenyl)methylsulfonamido)benzofuran-3-carboxamide (0.7 g, 1.164 mmol) in 1:1 EtOH/Ethyl acetate (10 mL) was added tin(II) chloride (1.324 g, 6.98 mmol). The reaction was heated at 70° C. for 3 h. Solvent was evaporated and the reaction was partitioned between EtOAc and water. The resulting semi viscous mass was filtered (6 h) and the solid obtained (0.5 g, 75%) was progressed as is to the next step. LCMS (m/z, ES+)=572 (M+H+).
