Abstract: | A method of synthesizing 2-acetylamino-7-hydroxy-6-phenylthio-3-carbethoxybenzob]thiophenes from 6-phenylthio-7-oxo-4,5,6,7-tetrahydrobenzob]thiophenes has been developed. A method is also proposed for synthesis of 7-phenylthiobenzothieno2,3-d]pyrimidines.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 4, pp. 534–536, April, 1991. |
