4
, R
5
and R
6
, which may be identical or different, are each (1) a hydrogen atom, (2) a nitro group, (3) a cyano group, (4) a halogen atom, (5) a hydrocarbon group which may be substituted, (6) an amino group which may be substituted, (7) a hydroxy group which may be substituted, or (8) a thiol group which may be substituted; and R
3
and R
4
, R
4
and R
5
, and R
5
and R
6
may respectively form a ring together with the adjacent carbon atom, or salt thereof.
