![Benzenesulfonamide, N-cyclopropyl-N-[1-(phenylmethyl)-4-piperidinyl]-3-(trifluoromethyl)-](/CAS/20210305/GIF/870655-93-9.gif)
Yield:870655-93-9 95%
Reaction Conditions:
with triethylamine in dichloromethane;
Steps:
3.a
N-Benzyl-4-cyclopropylaminopiperidine (5.0 g, 21.71 mmol) and triethylamine (3.6 mL, 26.05 mmol) were dissolved in dichloromethane (DCM, 100 mL). 3-Trifluoromethylbenzenesulfonyl chloride (3.47 mL, 21.71 mmol) was added and the resulting reaction mixture was stirred overnight. The mixture then was poured into potassium carbonate solution (200 mL), extracted with ether (2*200 mL), dried (MgSO4), and concentrated in vacuum to give a crude product as a yellow gum, which was purified by column chromatography on silica gel (hexane/EtOAc, 2:1). The title compound 13 was obtained (9 g, 95% yield) as a pale yellow gum. Rf=0.42 (UV detection).
