To a solution of tert-butyl 4-hydroxypiperidine-1-carboxylate (202 mg, 1 mmol) in anhyd THF (3 mL) was added NaH (60% in mineral oil, 53 mg, 1.32 mmol). The mixture stirred at room temperature for 30 min, then a solution of 2-(chloromethyl)-5-(2-(3,4-dichlorophenyl)propan-2-yl)-1-(4-fluorophenyl)-1H-imidazole (262 mg, 0.66 mmol) in THF (2 mL) was added. After stirring at ambient temperature overnight, the reaction was quenched by addition of MeOH and concentrated in vacuo. The residue was partitioned in water and EtOAc. The combined organic layers were washed with brine, dried over Na2SO4, concentrated in vacuo, and purified by column chromatography (silica, 0-90% EtOAc/Hex) to give tert-butyl 4-((5-(2-(3,4-dichlorophenyl)propan-2-yl)-1-(4-fluorophenyl)-1H-imidazol-2-yl)methoxy)piperidine-1-carboxylate as a white solid (215 mg, 60%).
