✦ Synopsis

Reaction of 3‐Dimethylamino‐2,2‐dimethyl‐2__H__‐azirine with 6‐Methyluracil; Crystal Structure of the Products

The reaction of 3‐dimethylamino‐2,2‐dimethyl‐2__H__‐azirine (1) with 6‐methyl‐uracil (4) in 2‐propanol at 80° yields the 4__H__‐imidazoje derivative 5 as the main product. This reaction is similar to the previously reported ones with heterocyclic compounds containing the sequence NHCONHCO. In the presence of water, 5 is easily hydrolyzed to 6. The structures of 5 and 6 have been established by X‐ray crystallography.
