Reaction of o-phenylenediamine with dehydracetic acid in different alcohols leads to 2-alkoxycarbonylmethyl 4-methyl 1,5-benzodiazepines , to 4-acetyl methylene 1,5-benzodiazepin-2-one , and to benzimidazoles and . This constitutes a novel and efficient synthesis of some benzodiazepine derivatives.
