METHOD FOR PRODUCING PYRAZOLE DERIVATIVE AND METHOD FOR PRODUCING ISOXAZOLE DERIVATIVE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a pyrazole derivative and a method for producing an isoxazole derivative each using an easily available raw material in the absence of an acid catalyst.SOLUTION: The method for producing a pyrazole derivative comprises performing a first step of mixing a terminal alkyne and a strong basic compound and then further mixing and reacting with an aldehyde compound, a second step of mixing and reacting an oxidizing agent and a weak basic compound after the first step, and a third step of mixing and reacting a hydrazine derivative after the second step to produce a pyrazole derivative.
