Preparation of 2-R 5-oxo 5-H 6 -N,N-diethylcarboxamide 7-phenyl 1,3,4-thiadiazolo-[3,2-a] pyrimidine through reaction of 2-R 5-Oxo 5-H6- ethyl carboxilate 7-phenyl -1, 3,4 - thiadiazolo-[3,2-a] pyrimidine with N,N-diethylamin have been discussed in the paper. These compounds have many medicinal properties and are used in allergy medication and in anti-microbial studies. The structures of the compounds were elucidated using NMR, 13C, IR- spectroscopy.
