## Abstract A new method was developed for the synthesis of 6,7‐dihydro‐5__H__‐pyrimido[4,5‐__e__][1,4]diazepin‐8(9__H__)‐one derivatives. The key to construct the pyrimido[4,5‐__e__][1,4]diazepine core is the intramolecular amidation of __N__‐((4‐amino‐6‐chloropyrimidin‐5‐yl)methyl)‐substituted am
