実験手順

1-Methyl-4-pyridinone (1.1 mole) is added to 1,3-dimethyl-5-pyrazolamine (1 mole). The reaction mixture is kept at a temperature between 70° C. and 80° C. for a period of about 8 hours. After distillation under vacuum the residue is poured into water and neutralized with NaOH 10%. The compound of the title is recovered by filtration. M.p. 262°-265° C.
