A NEW SYNTHESIS OF PYRIMIDO-as-TRIAZINE DERIVATIVES

The reaction of 5-arylazo-6-arylidenehydrazino-1,3-dimethyluracils (II), prepared by the diazotization of 6-arylidenehydrazino-1,3-dimethyluracils (I), with dimethylformamide dimethylacetal afforded the corresponding 3-arylfervenulins (3-aryl-6,8-dimethylpyrimido-as-triazine-5,7(6H,8H)-diones) (V).
