To a solution of 4-(4-isopropylbenzoyl)piperidine in N,N-dimethylformamide (100 mL), potassium carbonate (9.60 g, 69.5 mmol) and benzyl bromide (8.50 g, 71.5 mmol) were added, and the resulting mixture was stirred for 20 hours at room temperature. The mixture was poured into water, and extracted twice with ethyl acetate. The organic layers were combined, washed with an aqueous saturated sodium hydrogencarbonate, dried over magnesium sulfate, filtered, and concentrated under reduced pressure. The residue was crystallized from hexane to obtain the title compound (13.53 g, yield 66%).
