Abstract

Jan. 1981 Studies in the Synthesis and Interconversion of Isomeric Triazolothienopyrimidines C. J. Shishoo, M. B. Devani, G . . V . Ullas, S. Ananthan and V. S. Bhadti Department of Pharmaceutical Chemistry, L. M. College of Pharmacy, Ahmedabad 380 009, India Received March 21, 1980 ... 4-Hydrazinothieno[2,3-dJpyrimidines were cyclized with triethyl orthoformate and formic acid to give 1,2,4-triazolo[4,3-c]thieno[3,2-e]pyrimidines and 1,2,4-triazolo[2,3-c]thieno[3,2-e] ...
