Title compd. (I; R1, R3 = lower alkyl; R2, R4= lower alkoxy; x4 =halogen atom),useful as excellent antiphlogistic agent, was prepd. by reacting 1-(4-halogen-6'-lower alkyl-2'- pyrimidinyl)-3-lower alkyl-5-lower alkoxypyrazole with lower alkoxylation agent. Thus, 1-(4'-chkoro-6'-methyl-2'-pyrimidinyl)-3-methyl-5-methoxy pyrazole was added in the metal sodium dissolved methanol soln., refluxed and recrystallized to give 1-(4'-methoxy-6'-methyl-2-pyrimidinyl)-3-methyl-5-methoxypyrazole.
