A convenient one step synthesis of N-substituted 2-sulfanylimidazole from an isothiocyanate, an &agr;-aminocarbonyl compound and an alkyl halide or an activated aryl halide is described. Reaction of an isothiocyanate with an &agr;-aminocarbonyl compound affords a thiourea acetal intermediate, which without isolation or purification affords the desired N-substituted 2-sulfanylimidazole upon treatment with an alkyl halide or an activated aryl halide.
