  Abstract:  1-(4-Hydroxy-6-methyl-2-pyrimidinyl)-3-methyl-pirazolin-5-one has been condensed with heterociclic aldehydes, derivatives of 5-phenyl-furfural by Knoevenagel reaction, obtaining 4-(5-phenyl-furylidene) -1-(4-hydroxy-6-methyl-2-pyrimidinyl)-3-methyl 2-pyrazolin-5-ones (2a-h). The structures are been confirmed by elemental analysis and spectroscopic data.
