실험 절차

To a stirred mixture of 3-(4,4,6-trimethyl-1,2,3,4-tetrahydro-quinolin-2-yl)-phenylamine (135 mg, 0.5 mmol) in dichloromethane (3 mL) was added pyridine (60 mg, 0.75 mmol) in dichloromethane (2 mL) and 3-fluoro-benzenesulfonyl chloride (108 mg, 0.56 mmol) under nitrogen. The resultant mixture was stirred for 4 h. 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=12:1) to afford 80 mg of 3-fluoro-N-[3-(4,4,6-trimethyl-1,2,3,4-tetrahydro-quinolin-2-yl)-phenyl]-benzenesulfonamide as yellow solid (Yield: 38%). MS (ESI+APCI) M+1=425.2.
