The reaction of 5,6-diamino-l,3-dimethyluracil with 1,3-diaryl-2,3-dibromopropan-l-ones gave {3-(5-amino-6imino-l,3-dimethyluracil)chalcones, and conditions for their cyclocondensation to pyrimidinodiazepines were found. For substantiation of the reaction mechanism, the reaction of the diamine with
