Reaction Steps

To a stirred solution of 3-(4,4-dimethyl-6-trifluoromethyl-1,2,3,4-tetrahydro-quinolin-2-yl)-phenylamine (150 mg, 0.47 mmol) in pyridine (74 mg, 0.94 mmol) and dichloromethane (2 mL) at 0° C. was added dropwise a solution of ethanesulfonyl chloride (90 mg, 0.70 mol) in dichloromethane (1 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 ethanesulfonic acid [3-(4,4-dimethyl-6-trifluoromethyl-1,2,3,4-tetrahydro-quinolin-2-yl)-phenyl]-amide (143 mg, 74.1%) as a white solid. MS (ESI+APCI) M+1=413.1.
