Procedure

To a solution of 2-(4,4-dimethyl-6-(trifluoromethyl)-1,2,3,4-tetrahydroquinolin-2-yl)aniline (100 mg, 0.36 mmol) and pyridine (114 mg, 1.44 mmol) in anhydrous dichloromethane (5 mL) was added 2-fluorobenzene-1-sulfonyl chloride (70.1 mg, 0.36 mmol) at ice-bath. After addition, the resulting mixture was stirred at room temperature for 3 h. The reaction mixture was diluted with water, and extracted with dichloromethane. The combined organic layer was dried over anhydrous sodium sulfate, concentrated. The residue was purified by HPLC to give N-(2-(4,4-dimethyl-6-(trifluoromethyl)-1,2,3,4-tetrahydroquinolin-2-yl)phenyl)-2-fluorobenzenesulfonamide. LC/MS m/e obsd. (ESI+) [(M+H)+] 478.90.
