実験手順

Combine 1-(t-butoxycarbonyl)-4-(1-(2-fur-2-ylmethoxy-ethyl)-1H-benzimidazole-2-carbonyl)piperidine (1.0 mmol) and dioxane (10 mL). Cool in an ice bath. Slowly add a solution of hydrochloric aicd in dioxane (0.25 mL, 4M, 1.0 mmol). After 45 minutes, dilute the reaction mixture with dichloromethane and extract with saturated aqueous sodium bicarbonate solution. Separate the organic layer and extract with brine. Dry the organic layer over Na2SO4, filter, and evaporate in vacuo to give the title compound.
