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.
本发明提供了一种工业生产方法:制备具有杀虫效果的嘧啶化合物;2-[4-(三氟甲基)苯基]乙胺,它是嘧啶化合物的生产中间体;一种作为药用和农药中间体有用的苯乙胺化合物;以及进一步的作为苯乙胺化合物的生产中间体有用的3-芳基丙酰胺化合物和3-芳基丙酸酯化合物。通过在金属催化剂和还原剂存在下,将由式(1)表示的化合物(其中X代表氯原子或溴原子;Y代表可选地取代氟原子、氢原子、氟原子、氰基、烷基羰基、二烷基氨基基团等的烷基基团)与丙烯酰胺或丙烯酸酯反应,可以高效地并且工业化地在一步中生产3-芳基丙酰胺化合物或3-芳基丙酸酯化合物。
