and Ar
2
: a heteroaryl group or an aryl group; R
1
, R
2
and R
3
: a hydrogen atom, a halogen atom, a C1-C6 alkyl group, a halogenated C1-C6 alkyl group, a hydroxy C1-C6 alkyl group, a C1-C6 alkoxy C1-C6 alkyl group or a C3-C7 cycloalkyl group or a cyano group; R
4
and R
5
: a hydrogen atom, a halogen atom, a C1-C6 alkyl group, a halogenated C1-C6 alkyl group, a hydroxyl group, a hydroxy C1-C6 alkyl group, a C1-C6 alkoxy C1-C6 alkyl group, a C3-C7 cycloalkyl group or a C1-C6 alkoxy group;
n: an integer of 1 to 3; and
the heteroaryl or aryl group optionally has one or two groups independently selected from a halogen atom, a C1-C6 alkyl group, a halogenated C1-C6 alkyl group, a hydroxyl group, a hydroxy C1-C6 alkyl group, a C1-C6 alkoxy C1-C6 alkyl group, a C3-C7 cycloalkyl group, a carboxyl group, a cyano group, an amino group, a C1-C3 alkylamino group and a di-C1-C3 alkylamino group, and when the heteroaryl or aryl group has two such groups, the two groups are the same as or different from each other.
