A series of 2-alkylthio-4,5-diarylimidazoles were synthesized in three steps. The reaction of ammonium thiocyanate with benzoylbenzoins 4 gave 4,5-diarylimidazole-2-thiones 5. Alkylation of compound 5 with alkyl iodide yielded 2-alkylthio-4,5-diarylimidazoles 6. Chlorosulfonation of compound 6 followed by ammonia gave the desired compounds 4-[2-alkylthio-4(5)-(4-substituted phenyl)imidazole-5(4)-yl]benzensulfonamides 7.

potent, bioavailable ACAT inhibitor may have beneficial effects in the treatment of atherosclerosis by (i) reducing the absorption of dietary cholesterol, (ii) reducing the secretion of very low density lipoproteins into plasma from the liver, and (iii) preventing the transformation of arterial macrophages into foam cells. We have found that a mevalonate derivative 2, which contains a 4,5-diphenyl-1H-imidazol-2-yl
