Reaction Steps

To 4-chloro-5-(4-cyano-6-trifluoromethyl-pyridin-3-yl)-2-methoxy-benzenesulfonyl chloride (100 mg, 0.24 mmol) in dichloromethane (3 mL), was added pyridine (0.04 mL, 0.48 mmol), followed by addition of N-methylaniline (0.05 mL, 0.48 mmol). The mixture was stirred at r.t. for 16 hrs, then poured into 1 N HCl solution (10 mL). The product was extracted with ethyl acetate and the organic layer was washed with 1N HCl and water, then was dried over MgSO4. Concentration gave 4-chloro-5-(4-cyano-6-trifluoromethyl-pyridin-3-yl)-2-methoxy-N-methyl-N-phenyl-benzenesulfonamide 15-1, (108 mg). MS: 482.0 (M+H)+; tR=8.76 min (method 2).
