LACTAM AND AMIDE ACETALS. 56. SYNTHESIS OF PYRIMIDINES FROM N-CARBAMOYLAMIDINES

Dozorova, E. N.,Grizik, S. I.,Granik, V. G.

, p. 70 - 73 (1990)

N-Carbamoyl-N.N'-dimethylformamidine reacts with ethyl anthranilate to give quinazoline-2,4-dione, and with cyanoacetamide to give 4-amino-5-carbamoylpyrimidin-2-one.The reaction of dimethylacetamide diethyl acetal with urea proceeds via N-carbamoyl-N',N'-dimethylacetamidine with the subsequent formation of 4-dimethylamino-6-methyl-pyrimidin-2-one and 4,6-dimethyl-sym-triazin-2-one.
