Thermolysis of neat N‐carboethoxy‐3‐azido‐3‐ethylazetidine (3) at 200° under argon produced the corresponding cyclic imine 4 (68% yield). Prolonged refluxing of a mixture of N‐triflylazetidin‐3‐one (7), sodium azide, and titanium tetrachloride in acetonitrile solvent afforded recovered 7 (25% yield) along with a colorless microcrystalline solid, 8, mp 104–105° (20% yield), whose structure was established unequivocally via application of X‐ray crystallographic methods.
