Guccione, Salvatore published the artcileSynthesis of 3-methyl-substituted pyrazolotriazolopyrimidin-4-one and pyrazolothiazolopyrimidin-4-one derivatives, SDS of cas: 23286-70-6, the publication is Journal of Heterocyclic Chemistry (1996), 33(2), 459-463, database is CAplus.
As a part of a research on anti-inflammatory analgesic compounds 3-Me substituted pyrazolotriazolopyrimidin-4-one derivatives (R = Ph, 4-chlorophenyl) and pyrazolothiazolopyrimidin-4-one derivatives II (R1 = H, Br) were prepared by previously reported procedures. None of the compounds showed improved activity when compared with the previously reported unsubstituted analogs.
Journal of Heterocyclic Chemistry published new progress about 23286-70-6. 23286-70-6 belongs to pyrazoles-derivatives, auxiliary class Pyrazole,Amine,Ester, name is Ethyl 5-amino-3-methyl-1H-pyrazole-4-carboxylate, and the molecular formula is C7H11N3O2, SDS of cas: 23286-70-6.
