Article abstract of DOI:10.1016/0223-5234(91)90065-U

As an extension of a previous work, in which a series of 4-phenyl-2-thioxo-benzo<4,5>thieno<2,3-d>pyrimidines were synthesized, a new series of 3-amino derivatives of this ring system has been prepared.The products obtained together with those reported in
