Pyridine-based heterocycles. Synthesis of new pyrido [4',3':4,5]thieno[2,3- d]pyrimidines and related heterocycles

The synthesis of the title compounds was achieved using ethyl 2-amino-6methyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxylate (1) as starting material. The reaction of the amino ester 1 with phenylisothiocyanate in boiling ethanol afforded the thiou
