실험 절차

To a solution of 1-[(2S,3R)-2-benzyloxy-5-(6-quinolyloxy)-3-pentyl]imidazole-4-carboxamide (58 mg, 0.135 mmol) in cyclohexene (2.5 ml) and ethanol (5 ml) was added 20% palladium hydroxide on carbon (50 mg). The resulting mixture was stirred at reflux for 8 h. After cooling to room temperature, the mixture was filtered through Celite and washed with ethanol. The filtrate was concentrated in vacuo and then the residue was purified by silica gel (1.5 g) chromatography eluted with chloroform/methanol (50:1 to 10:1) to give 1-[(2S,3R)-2-hydroxy-5-(6-quinolyloxy)-3-pentyl]imidazole-4-carboxamide (2) (39.8 mg, 86.8%).
