Patent ID: 7906511

Claim:
A compound represented by the following general formula (1) or a salt thereof: wherein the ring X represents which may have one or plural substituents selected from a halogen atom and an alkyl group; R 1 and R 2 may be the same or different and each represents a hydrogen atom, an alkyl group, an aryl group or an aromatic heterocyclic group; in the case where R 1 or R 2 is an alkyl group, the alkyl group may have one or plural substituents selected from an aryl group, a halogenoaryl group, an alkoxyaryl group and an alkylaryl group; in the case where R 1 or R 2 is an aryl group, the aryl group may have one or plural substituents selected from a halogen atom, a hydroxy group, an alkoxy group, a halogenoalkoxy group, an alkyl group, a halogenoalkyl group, an aryl group, a halogenoaryl group, an alkoxyaryl group and an alkylaryl group; R 1 and R 2 may be combined together to form a nonaromatic heterocycle; R 3 represents a hydrogen atom, a halogen atom, a hydroxy group, an alkoxy group, an aryloxy group, an alkyl group, an aryl group, an amino group, an alkylamino group, a cycloalkylamino group, an arylamino group, an alkylcarbonylamino group, an arylcarbonylamino group, a mercapto group, an alkylthio group, an arylthio group, an alkylsulfinyl group or a nonaromatic heterocyclic group; in the case where R 3 is an alkylamino group or an alkylcarbonylamino group, the alkyl moiety of which may have one or plural substituents selected from a hydroxy group, an alkoxy group, an aryl group, an amino group, an alkylamino group and a nonaromatic heterocyclic group; in the case where R 3 is a cycloalkylamino group, the cycloalkyl moiety of which may have one or plural substituents selected from a hydroxy group and an alkoxy group; in the case where R 3 is a nonaromatic heterocyclic group, the ring of which may have one or plural substituents selected from an alkyl group, a hydroxyalkyl group and an alkoxyalkyl group; A 1 represents a sulfur atom, a sulfinyl group or a sulfonyl group; and A 2 represents an alkylene group.
