Reaction Steps

In 15 ml of cocentrated hydrochloric acid was dissolved 1.5 g (3.2 mmol) of the alcohol compound (130d), and the mixture was heated at 110° C. for 7 hours. After cooling, the mixture was neutralized with sodium hydrogen carbonate, extracted with ethyl acetate, the extract was washed with water, dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (3% methanol/ethyl acetate), and 1.14 g of 2-(5-(3,5-dichlorophenylthio)-2-(2-hydroxyethyl)-4-isopropyl-1H-imidazol-1-yl)ethanol (131c) was obtained as oil (yield 94%).
