## Abstract The reaction of 1‐aryl‐3‐(dimethylamino)‐1‐propanones 1 with one equivalent of 4,5‐diamino‐1__H__‐pyrimidin‐6‐ones 2, in acidic medium, leads to the formation of 4‐aryl‐2,3,6,7‐tetrahydro‐1__H__‐pyrimido[4,5‐__b__]‐[1,4]diazepin‐6‐ones 3. The structure elucidation of the products is bas
