摘要
The present invention relates to a method for preparing quinazoline derivatives by aerobic oxidation using oxygen as an oxidizing agent in dimethylsulfoxide (DMSO) solvent wherein metal and base are excluded. The method for preparing quinazoline derivatives according to the present invention does not require any metal catalyst such as palladium or iridium, and thus does not cause toxicity problem of residual metal; and does not require demanding processes such as strong acid, or base conditions, low temperature reactions, or reactions of anhydrous conditions and thus, it is possible to simply and economically prepare quinazoline derivatives by reacting anthranilamide derivatives and an aldehyde source.;COPYRIGHT KIPO 2015
