Disclosed is a process for producing a benzylamine derivative represented by the general formula (3): (see formula 3 ) wherein X1, R1 and R2 are as defined below, which comprises reacting a benzyl derivative represented by the general formula (1): (see formula 1) wherein X1 represents a halogen atom and R1 represents an acyl group, with a haloacyl compound represented by the general formula (2): R2- X2 (2) wherein X2 represents a halogen atom and R2 represents an acyl group, in the presence of Lewis acid. According to this method, a benzylamine derivative as an intermediate, which is useful for the preparation of a carbamate-based agricultural or horticultural bactericide, can be preferably prepared.

L'invention concerne un procédé de fabrication d'un dérivé benzylamine représenté par la formule générale (3), dans laquelle X?1¿ est halogéno et R?1¿ et R?2¿ sont acyle. Le procédé selon l'invention est caractérisé en ce qu'il consiste à faire réagir un composé benzyle représenté par la formule générale (1), dans laquelle X?1¿ et R?1¿ ont les significations données plus haut, avec un composé haloacyle représenté par la formule générale (2), dans laquelle X?2¿ est halogéno et R?2¿ a la signification donnée plus haut, en présence d'un acide de Lewis. Ainsi, il est possible de fabriquer de façon avantageuse ledit dérivé benzylamine qui est un intermédiaire servant à la production d'un bactéricide de type carbamate destiné à une utilisation agricole et horticole.
