Abstract
The synthesis of 3-amino-7-(ethoxycarbonylmethylthio)thieno[2,3-d:4,5-d′]-dipyrimidin-4(3H)-one was accomplished. 7-Substituted 3-aminothieno[2,3-d:4,5-d′]-dipyrimidin-4(3H)-ones were synthesized by its reaction with nucleophilic reagents — dimethylamine, morpholine, piperidine, hydrazine hydrate, and sodium hydroxide.
