Abstract

The present invention provides a method for industrially producing: a pyrimidine compound having pest control efficacy; 2-[4-(trifluoromethyl)phenyl]ethylamine which is a production intermediate of the pyrimidine compound; a phenylethylamine compound useful as a pharmaceutical and agrochemical intermediate; and further a 3-arylpropionamide compound and a 3-arylpropionic acid ester compound useful as production intermediates of the phenylethylamine compound. The 3-arylpropionamide compound or the 3-arylpropionic acid ester compound can be efficiently and industrially produced in a single step by reacting a compound represented by formula (1) (wherein X represents a chlorine atom or a bromine atom; and Y represents an alkyl group optionally substituted with fluorine atom(s), a hydrogen atom, a fluorine atom, a cyano group, an alkylcarbonyl group, a dialkylamino group, or the like) with acrylamide or an acrylic acid ester in the presence of a metal catalyst and a reducing agent.
