실험 절차

A mixture of benzyl 4-bromobutyrate (23.7 g), imidazole (8.1 g), potassium carbonate (14.0 g) and acetone (400 ml) was stirred under reflux for 6 hours. After cooling the mixture to room temperature, the insoluble material was filtered off, and the filtrate was concentrated. The residual oil was subjected to column chromatography on silica gel. The fractions eluted with ethyl acetate/methanol (20/1, v/v) gave benzyl 4-(1-imidazolyl)butyrate (7.3 g, 33%) as an oil.
