실험 절차

4-[2-(1-Benzhydryl-azetidin-3-yloxy)-phenyl]-piperazine-1-carboxylic acid tert-butyl ester (750 mg, 1.5 mmol) and ammonium formate (1.8 g, 30 mmol) were dissolved into methanol (50 mL) at r.t. The solution was added slowly to 10% palladium on carbon (750 mg) in methanol (20 mL) under nitrogen atmosphere. The mixture was stirred for about 48 hours and filtered through a bed of celite. The solvent was removed under reduced pressure to afford the title compound as a colorless oil (380 mg, 60%).
