In the present invention, the structure: (R1, R2, R3, R4 and R5 are each independently H, halogen, CF3 or C1-C4 alkyl, and two or more of R1, R2, R3, R4 or R5 are H. R6 is H, OH or halogen, and B is a substituted or unsubstituted heterobicycle, R1 is CF3, R2 is H, R3 is F, R4 is H, and R5 is H. Or R1 is H, R2 is CF3, R3 is H, R4 is CF3, and R5 is H, or R1 is Cl, R2 is H, R3 is H, R4 is F, and R5 is H. Or R1 is CF3, R2 is H, R3 is F, R4 is H, and R5 is H, or R1 is CF3, R2 is F, R3 is H, R4 is H, and R5 is H. Or when R1 is Cl, R2 is F, R3 is H, R4 is H and R5 is H , B is a compound having at which) other than, or a pharmaceutically-acceptable salt thereof. [Chemical 1]本発明は、構造:(R1、R2、R3、R4及びR5は、それぞれ独立に、H、ハロゲン、CF3又はC1~C4アルキルであり、R1、R2、R3、R4又はR5の2つ以上がH以外であり、R6はH、OH又はハロゲンであり、及びBは、置換又は無置換のヘテロ二環であり、R1がCF3、R2がH、R3がF、R4がH、及びR5がHであるか、又はR1がH、R2がCF3、R3がH、R4がCF3、及びR5がHであるか、又はR1がCl、R2がH、R3がH、R4がF、及びR5がHであるか、又はR1がCF3、R2がH、R3がF、R4がH、及びR5がHであるか、又はR1がCF3、R2がF、R3がH、R4がH、及びR5がHであるか、又はR1がCl、R2がF、R3がH、R4がH、及びR5がHである場合、Bは以外である)を有する化合物、又はその薬学的に許容され得る塩を提供する。【化1】
