Reaction Steps

To a stirred solution of 3-(4,4-dimethyl-6-trifluoromethyl-1,2,3,4-tetrahydro-quinolin-2-yl)-phenylamine (100 mg, 0.31 mmol) in pyridine (49 mg, 0.62 mmol) and dichloromethane (1.5 mL) at 0° C. was added dropwise a solution of 4-fluoro-benzenesulfonyl chloride (73 mg, 0.37 mmol) in dichloromethane (0.5 mL). The mixture was stirred at room temperature overnight. The mixture was quenched with water (5 mL) and extracted with dichloromethane (5 mL×2). The combined organic layers were dried over anhydrous sodium sulfate and evaporated. The residue was purified by column chromatography on silica gel to afford N-[3-(4,4-dimethyl-6-trifluoromethyl-1,2,3,4-tetrahydro-quinolin-2-yl)-phenyl]-4-fluoro-benzenesulfonamide (121 mg, 81.3%) as a white solid. MS (ESI+APCI) M+1=479.1.
