## Abstract Fused tricyclic 7‐phenyl‐5__H__‐thizolo[5,4‐__e__]pyrrolo[1,2‐__a__][1,4]diazepin‐10(9__H__)one (**10**) was prepared by thermolysis of 2‐phenyl‐4‐(1‐pyrrolylmethyl)thiazole‐5‐carbonyl azide (**9**) in acetic acid. In addition, starting from **10**, 7‐phenyl‐5__H__‐thiazolo [5,4‐__e__][
## 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
