Efficient microwave assisted synthesis of some new benzimidazoles containing the mebendazole nucleus

Abstract

A simple and practical method has been developed for the synthesis of benzimidazoles containing the biological active mebendazole nucleus. Iminoester hydrochlorides of phenylacetic acids were used as intermediates in the reaction with 3,4-diaminobenzophenone under microwave irradiation leading to the products in good yields and in short reaction times.
