Heating of 6-hydrazinouracil 1 in ethanol in the presence of hyrochloric acid results in the formation of N1, N2-bis(1,3-dimethyl-2,6-dioxopyrimid-4-yl)hydrazine 3, which gives the diazo derivative 4 on treatment with 2,4-diazido-6-cyanomethoxy-s-triazine in DMSO in the presence of triethylamine et room temperature Доп.точки доступа: Azev, Y.
