    Project supported by the National Natural Science Foundation of China (No. 21272266) and the National "Twelfth Five-Year" Plan for Science & Technology (No. 2011BAE06B05-5).

At room temperature, a new simple and efficient copper-catalyzed method for the synthesis of quinazolin- 4(3H)-ylidene derivatives containing carbonyl and ester group was developed. The targets were prepared using methyl 3-(2-bromophenyl)-3-oxopropanoate analogues and amidine hydrochlorides as the initial materials, cuprous iodide as catalyst, and potassium phosphate as base at the ligand-free condition. Their structures were confirmed by 1H NMR, 13C NMR and HRMS.

Key words: copper, room temperature, catalyst, quinazoline
