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.

An efficient synthesis of some novel 2-aroylimino-3-aryl-4-phenyl-1,3-thiazolines was carried out by base-catalyzed cyclization of 1-aroyl-3-arylthioureas with acetophenone in the presence of bromine. The structures were confirmed by spectroscopic data, elemental analyses, and in one case (2t) by single-crystal X-ray diffraction data.
