<P>PROBLEM TO BE SOLVED: To provide a production method of a 1-substituted-5-alkyl-1H-pyrazole-4-carboxylate through a synthesis route different from a conventional production method. <P>SOLUTION: The production method of a pyrazole compound includes allowing a 2-acyl-3-aminoacrylate expressed by general formula (1) to react with a substituted hydrazine expressed by general formula (4) under acidic conditions. In formula (1), R<SP POS="POST">1</SP>, R<SP POS="POST">2</SP>, R<SP POS="POST">3</SP>and R<SP POS="POST">4</SP>each independently represent an alkyl group; and in formula (4), R<SP POS="POST">5</SP>represents an alkyl group or a phenyl group. <P>COPYRIGHT: (C)2012,JPO&INPIT |
