2-Dimethylamino-4-(2-acetylhydrazino)- and 4-(2-benzoyl)hydrazino-6,7-dihydrooxazolo[3,2-a]-sym-triazines were synthesized. It was established that when these compounds are heated, they undergo rearrangement to the corresponding 2-dimethylamino-6,7-dihydroimidazo[2,1-a]-sym-triazines. Deacylation of the latter gives the N-amino derivative.
