Reaction Conditions

Reaction Steps

Added was 18 ml of cocentrated hydrochloric acid to 1.8 g (4.0 mmol) of the alcohol compound (118c), and the mixture was stirred with heating at 110° C. for 7 hours. After cooling, the mixture was neutralized with sodium hydrogen carbonate, and 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 (ethyl acetate) to give 960 mg of 2-(5-(3,5-dichlorophenyl-thio)-2-hydroxymethyl-4-isopropyl-1H-imidazol-1-yl)ethanol (119b) as oil (yield 67%).
