independently represent a hydrogen atom, halogen atom, a lower alkyl, aryl, lower alkoxy or monocyclic heterocyclic group which may be substituted or the like; R
6
represents a lower alkyl, aryl, monocyclic heterocyclic, bicyclic heterocyclic or tricyclic heterocyclic group which may be substituted; X
1
represents a lower alkylene group or the like; X
2
represents a lower alkylene, lower alkenylene or lower alkynylene group which may be substituted; X
3
represents an oxygen atom, sulfur atom, a sulfinyl group, sulfonyl group or the like; Y
1
represents a bivalent cyclic group, containing a nitrogen, which may be substituted or the like; and Z
