- the compound represented by formula (3) can be obtained in high yield.
- the term "unsubstituted” means that only a base group is used. When only the name of the mother nucleus group is described without the description of "substituted”, it means “unsubstituted” unless otherwise specified.
- the term “substituted” means that any hydrogen atom in a mother nucleus group is replaced with a group (substituent) having the same or different structure as that of the mother nucleus.
- a “substituent” is another group attached to a scaffold group.
- the number of substituents may be one, or two or more. Two or more substituents may be the same or different.
- C1-6 indicates that the number of carbon atoms in the mother nucleus group is from 1 to 6, and the like. This number of carbon atoms does not include the number of carbon atoms in substituent groups.
- a butyl group having an ethoxy group as a substituent is classified as a C2 alkoxy C4 alkyl group.
- a "substituent” is not particularly limited as long as it is chemically acceptable and has the effects of the present invention.
- C1-6 such as methyl group, ethyl group, n-propyl group, i-propyl group, n-butyl group, s-butyl group, i-butyl group, t-butyl group, n-pentyl group, n-hexyl group alkyl group; vinyl group, 1-propenyl group, 2-propenyl group (allyl group), 1-butenyl group, 2-butenyl group, 3-butenyl group, 1-methyl-2-propenyl group, 2-methyl-2-propenyl group, etc.
