Reaction Steps

To a stirred solution of 1-(3-trifluoromethyl-pyridin-2-yl)-piperazine (100 mg, 0.39 mmol) in anhydrous dichloromethane (2 mL) was added 4-benzyloxy-benzenesulfonyl chloride (110.27 mg, 0.39 mmol) then diisopropylethylamine (0.17 mL, 0.98 mmol). The mixture was stirred at room temperature for 4 hour. Reaction was complete as determined by TLC. The reaction mixture was purified with flash column chromatography to yield 1-{[4-(benzyloxy)phenyl]sulfonyl}-4-[3-(trifluoromethyl)pyridin-2-yl]piperazine in 78.9% yield (147 mg) as white solid.
