- MANUFACTURING METHOD OF PYRAZOLE DERIVATIVE AND INTERMEDIATE PRODUCTS THEREOF
-
PROBLEM TO BE SOLVED: To provide an improved manufacturing method of a compound expressed by a general formula (2) (in the general formula, R1, R2 or R3 is a (C1-C6) alkyl group), the compound useful as an intermediate product for a medical drug or an agricultural chemical, the improved manufacturing method desired due to a conventional manufacturing method of the compound (2) not being industrially advantageous in view of economical efficiency, environmental load and operation safety . SOLUTION: In a manufacturing method of a compound (2), a compound expressed by a general formula (5) (in the general formula, R1 and R2 are the same as in the above and X is a halogen atom) is successively or integrally reacted in a reaction vessel under a presence of bases.
