The present invention provides a method for producing a pyrimidinylpyrazole compound (1), wherein aminoguanidine (2) or its salt is reacted with a β-diketone compound (3) to produce the pyrimidinylpyrazole compound:
wherein R1 and R3 are each independently an alkyl group having 1 to 4 carbon atoms, and R2 is a hydrogen atom or an alkyl group having 1 to 4 carbon atoms. The method is excellent in the environmental compatibility and economic efficiency.
本发明提供了一种生产
嘧啶基
吡唑化合物(1)的方法,其中
氨基
胍(2)或其盐与
β-二酮化合物(3)反应,以产生
嘧啶基
吡唑化合物:其中R1和R3分别独立地是具有1至4个碳原子的烷基基团,而R2是氢原子或具有1至4个碳原子的烷基基团。该方法在环境兼容性和经济效益方面表现出色。
