Procedure

In ethyl acetate was dissolved 64 mg of 5-(3,5-dichlorophenylthio)-2-hydroxymethyl-4-isopropyl-1-(m-nitrobenzyl)-1H-imidazole (103b), and platinum sulfided carbon was added. After replacement with hydrogen atmosphere, the mixture was catalytically hydrogenated under atmospheric pressure at room temperature. After 3 hours, the mixture was filtered through Celite, the filtrate was distilled off under reduced pressure, and diethyl ether was added. Crystals precipitated were filtered, and 25 mg of Compound I-118 was obtained (yield 42%). mp 145-148° C.
