摘要

Abstract An efficient one??pot synthesis of 2??aryl??4 (3 H)??quinazolinones from 2??amino benzamides and substituted benzoyl chlorides in a room temperature ionic liquid is described. Compared with the classical reaction conditions, this new synthetic method has the advantages of recyclability of ionic liquid, very good to excellent yields (78–92%), the absence of hazardous and expensive catalysts, and easy workup procedures giving rise ...
