• The thermolysis of 6-(benzylidenehydrazino)uracil derivatives generally involves their oxidative cyclization to give the corresponding pyrazolo[3,4-<I>d</I>]pyrimidine derivatives. However, the thermolysis of fully methylated 6-(benzylidenehydrazino)uracils gave no pyrazolo[3,4-<I>d</I>]pyrimidines, but mixtures of the respective nitriles and 1,3-dimethyl-6-methylaminouracil. The photolysis of the fully methylated 6-(benzylidenehydrazino)uracils give the desired pyrazolo[3,4-<I>d</I>]pyrimidines.
