Diisopropylethylamine → 3-[4-(1-Methyl-1-{[3-(trifluoromethyl)phenyl]sulfonyl}ethyl)piperidin-1-yl]quinoline

Participants

Reaction Steps

To a 10 ml vial was added 4-(1-methyl-1-{[3-(trifluoromethyl)phenyl]sulfonyl}ethyl)piperidine (30 mg, 0.089 mmol), quinolin-3-ylboronic acid (62 mg, 0.358 mmol), copper acetate (32.5 mg, 0.179 mmol), diisopropylethyl amine (0.049 ml, 0.358 mmol) and 1 ml tetrahydrofuran. The resulting reaction mixture was stirred at room temperature for one hour then 60° C. 3 hours. After aqueous work up, the crude product was purified on reverse phase column eluted with water/acetonitrile gradient solvent to give 24 mg desired product as fluffy white solid after lyophilizing.
