    摘要： A method for producing a pyrazole compound represented by formula (1): (wherein R 1 represents an optionally substituted C 1-12 alkyl group, an optionally substituted C 3-12 cycloalkyl group, an optionally substituted C 6-16 aryl group, or an optionally substituted pyridyl group, R 2 and R 3 each independently represent a hydrogen atom, a halogen atom, a C 1-3 alkyl group, or a C 1-3 haloalkyl group), said method including a step in which a pyrazolidine compound represented by formula (2): (wherein R 1 , R 2 , and R 3 are as defined above) is reacted with a nitrite in the presence of an acid, allows a pyrazole compound to be produced industrially.

    摘要翻译： 式（1）所示的吡唑化合物的制造方法，式中，R 1表示可以具有取代基的C 1-12烷基，可以具有取代基的C 3-12环烷基，可以具有取代基的C 6-16芳基或 任选取代的吡啶基，R 2和R 3各自独立地表示氢原子，卤素原子，C 1-3烷基或C 1-3卤代烷基），所述方法包括以下步骤：将吡唑烷化合物 （2）表示的化合物：（其中R 1，R 2和R 3如上定义）与亚硝酸盐在酸存在下反应，允许工业生产吡唑化合物。
