(wherein, R
1a
represents an alkyl group having 1 to 6 carbon atoms or the like, R
1b
and R
1c
represent a hydrogen atom or the like, and X represents a chlorine atom, a bromine atom or an iodine atom)
can be produced by:
a step wherein a compound represented by formula (2):
is reacted with a compound represented by formula (3):
(wherein, each of R
2
and R
3

6
and R
7
independently represents an alkoxy group having 1 to 3 carbon atoms or the like),
thereby obtaining a compound represented by formula (4):
