## 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__][
The title compound, C~18~H~17~NO~2~, synthesized from enantiomerically pure L-proline, methyl chloroformate and a Grignard reagent, crystallizes with two molecules in the asymmetric unit. A chair conformation is adopted by the two fused five-membered rings.
