Disclosed is a process for producing a benzylamine derivative represented by the general formula (3):
wherein X
1
, R
1
and R
2
are as defined below, which comprises reacting a benzyl derivative represented by the general formula (1):
wherein X
1
represents a halogen atom and R
1
represents an acyl group, with a haloacyl compound represented by the general formula (2):
R
2
—X
2
(2)
wherein X
2
represents a halogen atom and R
2
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.
