The three‐dimensional structure of the title compound has been established by means of an X‐ray analysis. The product was formed by a thermal 1,3‐dipolar cycloaddition. According to the concerted [ π 4 s + π 2 s ]‐mechanism the formation of this stereoisomer should actually be forbidden. The structure determined by X‐ray analysis confirms the chemical results.
