Method for producing 3-arylpropionamide compound and 3-arylpropionic acid ester compound
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) ##STR00001##
(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.

Method for the synthesis and purification of aryl acid esters
The general inventive concepts are directed to the discovery that certain aryl acids can be esterified under particular conditions to provide the resulting ester as a solid that precipitates in good yield from the reaction mixture. The esters may then be isolated and purified with relative ease. Accordingly, a method for the esterification, isolation, and purification of aryl acids is provided.
