| titleOfInvention | Preparation of pyrazole derivatives and intermediates thereof |
| abstract | (57) [Problem] To provide a method for producing a pyrazole derivative and an intermediate thereof. SOLUTION: The benzoylmalonic ester derivative of the formula (VI) is subjected to a deesterification reaction, the compound is reacted with hydrazines of R 4 —NHNH 2 to form pyrazoles, and then reacted with halides of R 5 —Z. A process for producing a pyrazole derivative of the formula (I). Embedded image (In the formula, R 2 , R 3 , and R 4 are lower alkyl, R 5 is haloalkyl, and X and Z are halogen.) |
