The present invention relates to a compound represented by the formula:
wherein Ar is a phenyl group optionally having substituent(s), R
1
is a hydrogen atom, a hydrocarbon group optionally having substituent(s), an acyl group or a heterocyclic group optionally having substituent(s), R
2
is a hydrogen atom, a C
1-6
alkyl group optionally having substituent(s) or a C
3-6
cycloalkyl group optionally having substituent(s), Z is a methylene group optionally having a C
1-6
alkyl group, ring A is a piperidine ring optionally further having substituent(s), ring B and ring C are benzene rings optionally further having substituent(s), and R
