Procedure

To a solution of 3-(4-(aminosulfonyl)phenyl)-2-(4-fluorophenyl)thiophene-2-carboxylic acid (0.280 g) in quinoline (4.0 mL) was added Cu bronze (0.300 g). After 0.5 h at 180° C. under nitrogen, the reaction mixture was extracted with EtOAc and HCl 3N, dried over Na2SO4 and purified by flash chromatography (30% EtOAc in hexane) to give the title compound as a white solid (0.180 g).
