실험 절차

A mixture of 1-[4-(4-benzyloxyphenyl)butyl]imidazole (13.0 g), palladium-carbon (5%, 10.0 g) and ethanol (100 ml) was subjected to catalitic hydrogenation at room temperature under 1 atom. The catalyst was filtered off, and the filtrate was concentrated to give 1-[4-(4-hydroxyphenyl)butyl]imidazole (8.58 g, 94%). Recrystallization from ethyl acetate-hexane gave colorless prisms, mp 124-125° C.
