The reduction of 2,4-dichlorophenacyl chloride with NaBH4 gives 1-(2,4-dichlorophenyl)-2-chloroethanol (II), which is condensed with imidazole (III) to yield 1-(2,4-dichlorophenyl)-2-(N-imidazolyl)ethanol (IV). Finally, this compound is condensed with 4-(phenylthio)benzyl chloride (V) [prepared by chloromethylation of diphenyl sulfide (VI) with formaldehyde and HCl] using NaH as condensing agent.
