PURPOSE: Provided are an optically active or racemPURPOSE: Provided are an optically active or racemic intermediate compound for producing N-£1-(2,4-dic intermediate compound for producing N-£1-(2,4-dichlorophenyl)ethyl|-2-cyano-3,3-dimethylbutaneamiichlorophenyl)ethyl|-2-cyano-3,3-dimethylbutaneamide useful as a plant vermin exterminating agent, ade useful as a plant vermin exterminating agent, and a method for preparing the same. CONSTITUTION: nd a method for preparing the same. CONSTITUTION: The intermediate compound is optically active N-(aThe intermediate compound is optically active N-(alpha-methyl-2,4- dichlorobenzylidene)-alpha-(2,4-dlpha-methyl-2,4- dichlorobenzylidene)-alpha-(2,4-dichlorophenyl)ethylamine, which is obtained from tichlorophenyl)ethylamine, which is obtained from the condensation of optically active 1-(2,4-dichlorhe condensation of optically active 1-(2,4-dichlorophenyl)ethylamine with 2,4-dichloro acetophenone.ophenyl)ethylamine with 2,4-dichloro acetophenone. Alternatively, racemic N-(alpha-methyl-2,4-dichlo Alternatively, racemic N-(alpha-methyl-2,4-dichlorobenzylidene)-alpha- (2,4-dichlorophenyl)ethylamirobenzylidene)-alpha- (2,4-dichlorophenyl)ethylamine is obtained by subjecting optically active N-(ane is obtained by subjecting optically active N-(alpha- methyl-2,4-dichlorobenzylidene)-alpha-(2,4-dlpha- methyl-2,4-dichlorobenzylidene)-alpha-(2,4-dichlorophenyl)ethylamine to the action of an alkalichlorophenyl)ethylamine to the action of an alkali metal alkoxide in the presence of dimethyl sulfoi metal alkoxide in the presence of dimethyl sulfoxide. xide.
