Reaction Steps
Add tert-butyl 4-(4-(3-(trifluoromethyl)phenyl)-1H-imidazol-2-yl)piperidine-1-carboxylate (540 mg, 1.36 mmol) to diethyl ether (100 mL) and cool to 0° C. Add sodium hydride (55 mg, 1.5 mmol, 60% in mineral oil) to the mixture followed by methyl iodide (0.142 mL, 2.72 mmol). Stir the mixture for 1 h at 0° C. and warm to room temperature. Add THF (40 mL) and stir the mixture for 12 h. Concentrate the mixture, and purify the residue by silica gel chromatography (120 g RediSep column, elute with a gradient of 0% to 100% ethyl acetate:hexane, over 40 min, 85 mL/min) to provide tert-butyl 4-(1-methyl-4-(3-(trifluoromethyl)phenyl)-1H-imidazol-2-yl)piperidine-1-carboxylate (425 mg, 76%).
