SYNTHESIS OF 3-METHYL-SUBSTITUTED PYRAZOLOTRIAZOLOPYRIMIDIN-4-ONE AND PYRAZOLOTHIAZOLOPYRIMIDIN-4-ONE DERIVATIVES

摘要

As a part of a research on anti-inflammatory analgesic compounds 3-methyl substituted pyrazolotriazolopyrimidin-4-one and pyrazolothiazolopyrimidin-4-one derivatives were prepared by previously reported procedures. None of the compounds showed improved activity when compared with the previously reported unsubstituted analogs. [References: 19]
