実験手順
To 300 mg of 2-benzyloxymethyl-5-(3,5-dichlorophenylthio)-4-isopropyl-1-(3-(2-pyridyl)propyl)-imidazole was added 10 ml of ethanol and 20 ml of 36% hydrochloric acid, and the mixture was stirred at 90° C. for 2 hours. After completion of the reaction, the solvent was distilled off under reduced pressure, an aqueous sodium hydrogen carbonate solution was added, and extracted with ethyl acetate. The extract was dried over sodium sulfate, and the solvent was distilled off under reduced pressure. The residue was purified by silica gel chromatography (ethyl acetate:methanol=10:1) to give 127 mg of 5-(3,5-dichlorophenylthio)-4-isopropyl-2-hydroxymethyl-1-(3-(2-pyridyl)propyl)-1H-imidazole (yield 51%).
