Abstract

Reaction of 4(7)‐aminobenzimidazole with ethyl 2‐alkylmalonates gave the novel 4,5,6,7‐tetrahydro‐5‐alkyl‐imidazo[1,5,4‐ef][1,5]benzodiazepine‐4,6‐diones, and the 2‐alkyl‐4(7)‐(2′‐ethoxycarbonyl)acetamido‐benzimidazoles. The structure of all the products was corroborated by ir, mass spectrometry and ^1^H‐nmr.
