PROBLEM TO BE SOLVED: To provide a process for producing bis pyrazole derivative in which the operability is improved and bis pyrazole derivative can be produced in high yield and in high purity.SOLUTION: Provided is a process for producing bis pyrazole derivative in which a ketone derivative and a carboxylic acid derivative are reacted in the presence of a base in a solvent having a donor number of 25.0 to 35.0 to produce a bis β-diketone derivative, followed by, as exemplified in a reaction formula (3), the bis β-diketone derivative and a hydrazine derivative are reacted in a solvent containing an aprotic polar solvent having a relative dielectric constant of 30 or more.SELECTED DRAWING: None |
