Claim:
A compound represented by the formula (I) wherein represents a benzene ring or a naphthalene ring or a 6- to 10-membered monocyclic or bicyclic aromatic heterocycle; R 1 represents a hydrogen atom, methyl group, trifluoromethyl group, difluoromethyl group, fluorine atom or chlorine atom; R 2 represents a hydrogen atom, C 1-10 alkyl group optionally substituted with 1 to 6 of R 11 , C 2-10 alkenyl optionally substituted with 1 to 6 of R 11 , or C 2-10 alkynyl optionally substituted with 1 to 6 of R 11 ; R 11 represents (i) a halogen atom, (ii) OR 8 , where R 8 is (1) a hydrogen atom, (2) C 1-3 alkyl group, (3) C 1-3 haloalkyl group, (4) a C 5-6 carbocycle, (5) a 5- to 6-membered heterocycle containing 1 to 2 nitrogen atoms, 1 oxygen atom and/or 1 optionally oxidized sulfur atom, or (6) C 1-3 alkyl group substituted with a hydroxyl group, C 1-3 alkoxy group or NR 9 R 10 , where R 9 and R 10 each independently represent a hydrogen atom, C 1-3 alkyl group or phenyl group, (iii) NR 9 R 10 , where R 9 and R 10 each independently represent a hydrogen atom, C 1-3 alkyl group or phenyl group, (iv) a C 5-6 carbocycle optionally substituted with at least one selected from a halogen atom, oxo group and methyl group, or (v) a 3- to 10-membered heterocycle containing 1 to 4 nitrogen atoms, 1 to 2 oxygen atoms and/or 1 to 2 optionally oxidized sulfur atoms, optionally substituted with at least one group selected from a halogen atom, an oxo group and a methyl group; R 3 represents a hydrogen atom, methyl group, or fluorine atom; R 4 represents a hydrogen atom, C 1-2 alkyl group, C 1-2 haloalkyl group, or halogen atom; R 5 represents a hydrogen atom, C 1-3 alkyl group, C 1-3 haloalkyl group, or halogen atom; R 6 represents a hydrogen atom, C 1-3 alkyl group, C 1-3 haloalkyl group or halogen atom; R 7 represents a hydrogen atom, C 1-4 alkyl group, allyl group, trichloroethyl group, benzyl group, phenacyl group, p-methoxybenzyl group, trityl group, or 2-chlorotrityl group; p is an integer of 1 to 3; q is an integer of 1 to 4; and r is an integer of 1 to 6; and wherein: when p represents 2 or more, each R 4 may independently be the same or different, when q represents 2 or more, each R 5 may independently be the same or different, and when r represents 2 or more, each R 6 may independently be the same or different, or a salt thereof, an N-oxide thereof, or a prodrug thereof.
