SODIUM SULFIDE-PROMOTED REACTION OF 2-AMINOBENZAMIDE AND BENZYL ALCOHOLS WITH ELEMENTAL SULFUR: A NOVEL APPROACH WITH 2-ARYL-QUINAZOLIN-4(3H)

Abstract

A simple metal- and solvent-free method for the synthesis of 2-aryl- 4(3H)-quinazolinone derivatives from 2-aminobenzamide and benzyl alcohols in the presence of S8\DMSO as an oxidizing agent and promoted by Na2S.5H2O has been reported. Five 2-aryl-4(3H)-quinazolinone derivatives were synthesized with yields from 23% to 86%.
