Reaction of N,N-dimethylcarbamoyl bromide with 1,2,4-triazines

The acylation of substituted 1,2,4-triazines with N,N-dimethylcarbamoyl bromide was studied. 4,5-Dihydro-4-(N,N-dimethylcarbamoyl)-3-thioxo(oxo)-5-oxo-6-R-1,2,4-triazines were synthesized. The spectral characteristics of the synthesized compounds are discussed.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 7, pp. 969–971, July, 1989.
