Brzozowski, Zdzislaw published the artcileDerivatives of pyrazole-1-carboxylic acid. V. Syntheses of some derivatives of N-{4-[2-(pyrazole-1-carboxamido)ethyl]benzensulfonyl}-2-pyrazoline-1-carboxamide, Category: pyrazoles-derivatives, the publication is Acta Poloniae Pharmaceutica (1982), 39(1-3), 15-19, database is CAplus.
Twenty-five title compounds I (R-R6 = H, Me, and Et in various combinations) were prepared in 17-73% yields in the reaction of II with appropriately substituted pyrazole-1-carboxylic acid chlorides in the presence of 40% aqueous NaOH. Nine of them showed a moderate hypoglycemic activity in exptl. rats.
Acta Poloniae Pharmaceutica published new progress about 53355-55-8. 53355-55-8 belongs to pyrazoles-derivatives, auxiliary class Pyrazole,Chloride,acyl chloride,Amide, name is 1H-Pyrazole-1-carbonyl chloride, and the molecular formula is C4H3ClN2O, Category: pyrazoles-derivatives.
