To the reaction mixture, a saturated aqueous sodium hydrogen carbonate solution was added, extracted with methylene chloride, the extract was washed with water and dried, and the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate)to give 500 mg of 2-hydroxymethyl-5-(3,5-dichlorophenylthio)-4-isopropyl-1-(quinolin-3-ylmethyl)-1H-imidazole (109)(yield 83%). mp 174-175° C.
