Abstract
The condensation of 2-nitrobenzyl alcohols with arylacetic acids provides substituted quinazolines under mild conditions in the presence of urea as a nitrogen source, elemental sulfur as a promoter, DABCO as a base, and DMSO as a solvent. The reaction tolerates functionalities such as chloro, fluoro, trifluoromethyl, thienyl, and indolyl groups.
