Patent ID: 7217722

Claim:
A compound represented by formula (I) or a pharmaceutically acceptable salt or solvate thereof: Het—X—Z (I) wherein Het represents wherein R 12 represents a hydrogen atom or a halogen atom; X is —N(—R 1 )—Q6-Q7- wherein R 1 represents a hydrogen atom, Q6 represents a five- to seven-membered saturated heterocyclic group and the heterocyclic groups are optionally substituted by an oxygen atom, hydroxyl, or C 1-4 alkyl, Q7 represents —(CH 2 )n1-CR 2a R 2b —(CH 2 )n2- wherein n1 and n2 are each an integer of 0 to 3, when n2 is 2 or 3, —CH 2 —CH 2 — in —(CH 2 )n2- may represent —CH═CH— or —C≡C—, R 2a and R 2b , which may be the same or different, represent a hydrogen atom, a halogen atom, C 1-6 alkyl optionally substituted by hydroxyl, carboxyl, C 1-4 alkoxycarbonyl, cyano, Z represents a hydrogen atom, a halogen atom, a three- to seven-membered saturated or unsaturated monocyclic carbocyclic or heterocyclic group, a nine- to twelve-membered bicyclic saturated or unsaturated carbocyclic or heterocyclic group, or a thirteen- to fifteen-membered tricyclic saturated or unsaturated carbocyclic or heterocyclic group, wherein the carbocyclic and heterocyclic groups are optionally substituted by a halogen atom; hydroxyl; nitro; amino; C 1-4 alkyl optionally substituted by a halogen atom; C 1-4 alkoxy of which the alkyl portion is optionally substituted by a halogen atom; C 1-4 alkoxycarbonyl of which the alkyl portion is optionally substituted by a halogen atom; C 1-4 alkylcarbonyl of which the alkyl portion is optionally substituted by a halogen atom; C 1-4 alkylcarbonyloxy of which the alkyl portion is optionally substituted by a halogen atom; or benzyloxy of which the phenyl portion is optionally substituted by a halogen atom.
