Synthesis of 1-Aryl-6,7,8,9-tetrahydrobenzothienothiazolopyrimidin-5(H)-ones

1-Aryl-6,7,8,9-tetrahydrobenzothienothiazolopyrimidin-5(H)-ones (IIa-e) have been synthesised by the condensation of ethyl 2-amino-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate with α-thiocyanoacetophenones.Various intermediates have been isolated and their structures established on the basis of IR and PMR data.The course of reaction has also been rationalized.
