Procedure

To a stirred mixture of 3-(4,4,6-trimethyl-1,2,3,4-tetrahydro-quinolin-2-yl)-phenylamine (150 mg, 0.56 mmol) and pyridine (90 mg, 1.14 mmol) in dichloromethane (6 mL) was added 4-fluoro-benzenesulfonyl chloride (120 mg, 0.62 mmol) under nitrogen. The resultant mixture was stirred overnight. The reaction mixture was diluted with dichloromethane, washed with water (twice), saturated brine, and dried over magnesium sulfate. Magnesium sulfate was removed by filtration, and after evaporation, the residue was purified on chromatography column (silica gel, petroleum ether: ethyl acetate=10:1) to afford 100 mg of 4-fluoro-N-[3-(4,4,6-trimethyl-1,2,3,4-tetrahydro-quinolin-2-yl)-phenyl]-benzenesulfonamide as yellow solid (Yield: 42%). MS (ESI+APCI) M+1=425.2.
