An efficient method for the synthesis of S-aryl/heteroaryl-quinazoline has been developed through the cross-coupling of 1,4-dihydroquinazoline with a variety of aryl and heteroaryl boronic acids assisted by [Cu(OAc)₂] as the catalyst for the formation of carbon-sulfur bonds. This newly developed method demonstratesthat the conditions of the traditional copper-catalyzed Chan-Lam reaction can be improved. Optimized reaction involves base, solvent and catalyst.
