Procedure
To a solution of 1-benzo[1,3]dioxol-5-yl-cyclopropanecarbonyl chloride (0.97 mmol) in CH2Cl2 (3 mL) at ambient temperature was added a solution of 3′-amino-N-methylbiphenyl-4-sulfonamide (0.25 g, 0.97 mmol), Et3N (0.68 mL, 4.9 mmol), DMAP (0.050 g, 0.058 mmol), and CH2Cl2 (1 mL) dropwise. The mixture was allowed to stir for 16 h before it was diluted with CH2Cl2 (50 mL). The solution was washed with 1N HCl (2×25 mL), sat. aq. NaHCO3 (2×25 mL), then brine (25 mL). The organics were dried over Na2SO4, filtered, and concentrated in vacuo. The residue was purified by column chromatography (5-25% EtOAc/hexanes) to provide 1-benzo[1,3]dioxol-5-yl-N-[3-[4-(methylsulfamoyl)phenyl]phenyl]-cyclopropane-1-carboxamide as a white solid. ESI-MS m/z calc. 450.5, found 451.3 (M+1)+. Retention time of 3.13 minutes.
