<p><P>PROBLEM TO BE SOLVED: To provide an industrially applicable method for synthesizing a 2-(3-pyrazolyloxymethylene)nitrobenzene derivative. <P>SOLUTION: The 2-(3-pyrazolyloxymethylene)nitrobenzene derivative is represented by formula I [wherein, R<SP>1</SP>is a halogen atom, or a (substituted) alkyl or alkoxy; R<SP>2</SP>is a cyano, a halogen atom, an alkyl, a haloalkyl, an alkoxy, an alkylthio or an alkoxycarbonyl group; R<SP>3</SP>is an (substituted) alkyl, an alkenyl or an alkynyl, an (substituted) carbocyclic group or hetrocyclic group, being saturated or unsaturated at one or two position(s), or a (substituted) aryl or heteroaryl group; m is 0, 1 or 2, when m is >1, R<SP>2</SP>groups may differ from each other, and when n is 0-3 or 4 and >1, R<SP>1</SP>groups may differ from each other]. The 2-(3-pyrazolyloxymethylene)nitrobenzene derivative is produced by conducting a reaction between the corresponding brominated o-nitrobenzyl derivative and a 3-hydroxypyrazole derivative. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
