A compound represented by the general formula (I): ** Formula ** or a pharmaceutically acceptable salt thereof in which R 1 represents a heterocyclic group selected from a pyrazolyl group and a pyrimidinyl group, a heterocyclic group that may be substituted with 1 to 4 groups independently selected from substituent group A; R2 independently represents a halogen atom or a C1-6 alkyl group; n represents 0, 1 or 2; and substituent group A represents the group consisting of halogen atoms, C1-C6 alkyl groups, halogenated C1-C6 alkyl groups, C1-C6 alkoxy groups, a carboxy group, C2-C7 carboxy alkyl groups, C2-C7 alkylcarbonyl groups, groups C2-C7 alkoxycarbonyl, a cyano group, C1-C6 alkylsolfonyl groups, groups represented by the formula -C (> = O) -NR3R4 (R3 and R4 are identical or different from each other and each independently represents a hydrogen atom, a C1-6 alkyl group or a C3-C6 cycloalkyl group, or R3 and R4 form a saturated 4- to 6-membered heterocyclic ring together with the nitrogen atom attached thereto, in which the 4 to 6-membered saturated heterocyclic ring can also contain an oxygen atom), C2-C7 monoalkoxycarbonylamino groups and an oxo group. |
