ABSTRACT
The 2, 3-di-substituted quinazolin-4-(3H)-ones (III) have been synthesized as a one pot procedure from the reaction of Anthranilic acid (I), acid chlorides and primary amines with the intermediate 4-(3H)-benzoxazinone (II) at different microwave conditions. High yield, less by products, short reaction time (7-10 min), mild conditions and easy work-up are the advantages of this methodology.
Keywords : Microwave assisted one pot synthesis, 2, 3-di-substituted quinazolin-4-(3H)-ones.
