Abstract

PURPOSE: To obtain the titled compound useful as a herbicide and its intermediate in high yield and in high purity, by reacting a nitrodiphenyl ether type compound with a hydrazine derivative in the presence of an alcohol type organic solvent, followed by recovering the solvent easily.
CONSTITUTION: In the presence of an alcohol type organic solvent (e.g., n-propyl alcohol, etc.), a compound shown by the formula I (A and B are halogen, lower alkyl, etc.; m and n are m+n=1-3; D is nitro, etc.) is reacted with a compound shown by the formula II (R1, R2, and R3 are H, alkyl, substituted alkyl, etc.), to give a compound (e.g., 2-chloro-4-trifluoromethyl-3'-hydrazino-4'-nitrodiphenyl ether, etc.) shown by the formula III. The amount of the solvent used is 1W 50pts.wt., preferably 2W20pts.wt. based on 1pts.wt. compound shown by the formula I. A compound shown by the formula IV (R4W6 are H, etc.; n' is 2W5) having highly herbicidal activity is obtained easily from the compound shown by the formula III.
