PROBLEM TO BE SOLVED: To provide a compound which selectively activates estrogen receptor β. [Solution] A compound represented by the following formula (1) or a salt thereof. [Chemical 1] [0133] [In the formula, X represents a hydrogen atom or a group R 1 (wherein R 1 represents a chlorine atom, a bromine atom or a nitro group), Y represents a hydrogen atom or a group R 2 (wherein R 2 represents the number of carbon atoms). An alkyl group having 1 to 6 carbon atoms, an alkenyl group having 2 to 6 carbon atoms, a fluorine atom, a bromine atom, a hydroxy group, a nitro group, a cyano group, or an amino group which may be substituted with an alkyl group having 1 to 3 carbon atoms. W) and W and Z each represent a hydrogen atom or a fluorine atom. However, when one of X and Y is a hydrogen atom and the other is a group R 1 or a group R 2 , and Y is a fluorine atom or a methyl group, X and Z are not simultaneously a hydrogen atom. ] [Selection diagram] None【課題】エストロゲン受容体βを選択的に活性化する化合物の提供。【解決手段】 下記式（１）で示される化合物又はその塩。【化１】 【０１３３】〔式中、Ｘは水素原子又は基Ｒ１（ここで、Ｒ１は塩素原子、臭素原子又はニトロ基を示す）を示し、Ｙは水素原子又は基Ｒ２（ここで、Ｒ２は炭素数１～６のアルキル基、炭素数２～６のアルケニルキ基、フッ素原子、臭素原子、ヒドロキシ基、ニトロ基、シアノ基、又は炭素数１～３のアルキル基で置換されていてもよいアミノ基を示す）を示し、Ｗ及びＺはそれぞれ水素原子又はフッ素原子を示す。但し、Ｘ及びＹはいずれか一方が水素原子で他方が基Ｒ１又は基Ｒ２であり、Ｙがフッ素原子又はメチル基である場合、Ｘ及びＺは同時に水素原子ではない。〕【選択図】なし
