Abstract

Abstract 2-Carbomethoxybenzoyl chloride reacted with some 5-methylamino-l-phenyl-3-R- pyrazoles to yield N-methyl-l-phenyl-3-R-pyrazol-5-yl)-2-carbomethoxybenzamides. These products were readily transformed into the corresponding acid, which in turn, refluxed in phosphorus oxychloride afforded the tricyclic system, l-phenyl-3-R-pyrazolo [3, 4-b] benzazepine-4, 9-dione.
