1. Claim 1: a method for producing formula compound (1), which is characterized in that formula compound (2) reacts with formula compound (3): m (or1) V (3)；Symbol in formula (1)(2) And (3) are defined as follows: R1 refers to hydrogen, C1-6 hydrocarbon or phenyl group； in this case, C1-6 hydrocarbon can be replaced by one or more halogens, provided that when two or more halogens are replaced, the halogens may be the same or different； One or more alternatives in group 1 may be selected selectively in the phenyl group, provided that in the case of two or more alternatives, the alternatives may be the same or different； group 1 includes the halogen, cyanogen, nitrogen, C1-6 tar groups, 1. One alcoxi C1-6 and one group (alcoxi C1-6) - C1-6 tar；in group 1, the C1-6 alkyl group, the C1-6 alkoxy group and the C1-6 alkoxy-C1-6 alkyl group may be optionally substituted with one or more halogens, provided that, when substituted with two or more halogens, then the halogens can be the same or different； R 2 represents hydrogen, a C 1-6 alkyl group, a C 1-6 alkoxy-C 1-6 alkyl group, a C 2-6 alkenyl group, a C 2-6 alkynyl group, a C 3-6 cycloalkyl group, a group (alkyl C1-6-thio) -C 1-6 alkyl, a group (C 1-6 alkyl-sulfinyl) -C 1-6 alkyl, a group (C 1-6 alkyl-sulfonyl) -C 1-6 alkyl, a phenyl group or a group 5- or 6-membered heteroaryl； wherein the C1-6 alkyl group,the group (C1-6 alkoxy) -C1-6 alkyl, the C2-6 alkenyl group, the C2-6 alkynyl group, the C3-6 cycloalkyl group, the group (C1-6-thio alkyl) -C1-6 alkyl , the group (C1-6 alkyl-sulfinyl) -C1-6 alkyl and the group (C1-6 alkyl-sulfonyl) -C1-6 alkyl may be optionally substituted with one or more halogens, provided that when they are substituted with two or more halogens, then the halogens can be the same or different； and the phenyl group and the 5- or 6-membered heteroaryl group may optionally have one or more substituents selected from group 2, provided that, when they have two or more substituents, then the substituent
