실험 절차

To 4-(4-(4-fluoro-3-(trifluoromethyl)phenyl)-1H-imidazol-2-yl)piperidine hydrochloride salt (1510.00 mg; 3.91 mmol; 1.00 eq.) in DCM was added Ethyldiisopropylamine (2.81 ml; 15.64 mmol; 4.00 eq.) and stirred for 5 mins. N-(Benzyloxycarbonyloxy) succinimide (1169.26 mg; 4.69 mmol; 1.20 eq.) was then added. The reaction mixture was stirred at RT overnight. The reaction mixture was diluted with DCM, washed with water, 5% NaHCO3 aq and brine. The organic layer was dried and concentrated. The residue was subjected to SNAP column (100 g), eluted with 20-80% EA in hexane to afford the title compound (1310 mg, yield 74.9%).
