実験手順

(6)In 45 ml of ethanol was dissolved 9.10 g (20.1 mmol)of 5-(3,5-dichlorophenylthio)-1-methyl-4-isopropyl-2-(p-methoxybenzyloxymethyl)-1H-imidazole (17b), followed by addition of 90 ml of 6N-hydrochloric acid, and the mixture was refluxed for 1 hour. This reaction mixture was concentrated under reduced pressure to remove ethanol and the residue forming a couple of layers was extracted twice with n-hexane to remove p-methoxybenzyl chloride. The aqueous layer was extracted with methylene chloride and the extract was neutralized with an aqueous sodium bicarbonate solution and dried over magnesium sulfate. The solvent was then distilled off under reduced pressure and the residue was rinsed with isopropyl ether to provide 6.3 g (yield 95%)of [5-(3,5-dichlorophenylthio)-4-isopropyl-1-methyl-1H-imidazol-2-yl]methanol (12=Compound I-8). mp 157-158° C.
