Esterification of 4-isopropyl-1-(4-pyridylmethyl)-1H-imidazol-2-ylmethanol (XVIII) by means of acetyl chloride and triethylamine in dichloromethane gives the acetate ester (XX), which is condensed with 3,5-dichlorophenylsulfanyl chloride (XVII) by means of triethylamine in toluene/acetonitrile to yield the thioether (XXI). Hydrolysis of the acetate group of compound (XXI) by means of NaOH in ethanol affords the hydroxymethyl compound (XII), which is finally condensed with chlorosulfonyl isocyanate in acetonitrile.
