• R4 and R5 each independently represent a hydrogen atom, a C1-4 alkyl group, or a C1-4 acyl group;
• p represents an integer of 0 to 7;
• R3 represents a C1-4 alkyl group, a C2-4 alkenyl group, a C2-4 alkynyl group, a (C3-6 cycloalkyl)-(CH2)r— group, or a (3- to 6-membered saturated heterocycle)-(CH2)s— group, said R3 may be substituted with a halogen;
• r represents an integer of 0 to 4;
• s represents an integer of 0 to 4;
• Ring 2 represents a 3- to 15-membered ring;
• R2 represents a halogen, an oxo group, a hydroxyl group, a cyano group, C(O)R6, SO2R7, a C1-4 alkyl group, or a C1-4 alkoxy group,
• said C1-4 alkyl group or C1-4 alkoxy group may be substituted with a substituent selected from the group consisting of a halogen, a hydroxyl group, a cyano group, C(O)R8, NR9R10, and SO2R11;
• R6 represents a hydroxyl group, a C1-4 alkyl group, a C1-4 alkoxy group, or NR12R13;
