실험 절차

Combine tert-butyl 4-(4-bromo-1-(2-(methylsulfonyloxy)ethyl)-1H-imidazol-2-yl)piperidine-1-carboxylate (4.45 g, 9.84 mmol), dimethylformamide (25 mL), and pyrrolidine (2.46 mL, 3.0 eq) under nitrogen. Heat the reaction mixture at 50° C. overnight, then allow to cool to room temperature. Dilute with ethyl acetate. Wash with water followed by saturated aqueous sodium chloride. Dry the organics over anhydrous magnesium sulfate, filter, and concentrate in vacuo to give the title compound (4.12 g, 98%). MS (ES) m/z=427 [M]+.
