efficient, straightforward synthesis of somenew2-(4-methylbenzoylimino)-3-aryl-4-methyl-1,3-thiazolines (2a-i) is described. The methodology involves the cyclization of 1-(4-methylbenzoyl)-3-arylthioureas with acetone in the presence of bromine and triethylamine. The structures were confirmed by spectroscopic data, elemental analyses and in one case (2i) by the single crystal X-ray diffraction data.

Three series of new 1-(isomeric methyl)benzoyl-3-arylthioureas (1–3a–i) were prepared from 2-, 3-, and 4-methylbenzoyl chlorides via isothiocyanate formation followed by treatment with various substituted anilines. The base-catalyzed condensation of thioureas (1–3a–i) with acetone was carried out in the presence of bromine to afford the corresponding 1-(isomeric methyl) benzoyl-3-aryl-4-methyl-imidazole-2-thiones
