Several 3-substituted-(un)-cyclohepta(b)thieno[2,3-d]pyrimido[3,4-a]-1,2,4-triazoles 10 , 11 , 12 , 13 , and 14 were prepared by reaction of an appropriate substituted 2-amino-3-cyanothiophene 1 with aliphatic acids or benzoyl chloride. Also the fusion of 1 with urea, thiourea to give the corresponding 2-oxo or thioxo-4-aminopyrimidine derivatives 6a , b and other reactions of compound 1 are reported.
