摘要

Disclosed herein is a process for producing N-alkylpyrazoles represented by the formula (1), which comprises reacting an alkali metal or an alkali metal-containing base with N- unsubstituted pyrazoles represented by the formula (2), to form an alkali metal salt thereof and, subsequently, reacting the obtained alkali metal salt with an alkylating agent. <IMAGE> R1: H, C1-C4 alkyl R2: C1-C4 alkyl n: an integer of 1-3
