Abstract

Quinazoline-4-ones and their derivatives are well known for their pharmacological activity [1]. Their synthesis mostly starts from anthranilic acid derivatives, in particular their N- acylamides [2, 3]. The aim of the present work is to synthesize the sulfur analogues of N- benzoylaminoanthranilamides and to carry out their ring closure to the corresponding 2- phenyl-3-methylquinazoline-4-thiones, which could show biological activity too [4, 5]. ...
