In our reinvestigation of the cyclocondensation reaction of aminoguanidine bicarbonate 1 with 2-acetylbutyrolactone 2 and ethyl cyclohexanone-2-carboxylate 6, we have obtained the respective 1-amidino-3-pyrazolin-5-one derivative 3 and the 2-amidino-1, 2, 4, 5, 6, 7- hexahydro-3H-indazol-3-one 7. These intermediates were utilized for the synthesis of two novel series of 1-(pyrimidin-2-yl)-3-pyrazolin-5-ones and 2-(pyrimidin-2-yl)-1, 2, 4, 5, 6, 7- ...
