  Synthesis and Reactions of Some New Thienopyrimidines

  摘要：

  4-Methyl-6-mercapto-2-phenylpyrimidine-5-carbonitrile (1) was reacted with, different halo compounds, namely ethylchloroacetate, chloroacetone, bromoacetanilide, p-chlorobromoacetanilide, and p-methoxy chloroacetanilide in ethanol in the presence of sodium acetate yielded the corresponding S-alkylated derivatives (2a-e). The latter compounds underwent cyclization into thienopyrimidines (4a-e) upon treatment with sodium ethoxide in ethanol. The reaction of (4a) with hydrazine hydrate led to the formation. of 5-amino-4-methyl-2-phenylthieno[2,3-d]pyrimidine-2-carbohydrazide (5). Compound (5) was reacted with a variety of reagents to produce other new thienopyrimidines as well as oxadiazolylthienopyrimidines (6, 11).
