imidazolone derivative (2). However, carrying out the same reaction in absolute ethanol and in the presence of piperidine as a base gave the benzamide derivative (4). Fusion of (1a) with p‐anisidine gave the open adduct benzamide (6), which cyclized in acidic medium to give imidazolone derivative (7). Heating of imidazolone (7) with malononitrile above its melting point afforded 1,3‐diazepine derivative (8)
