To provide a novel salt and polymorph form of omecamtiv mecarbil useful as a therapeutic agent of cardiac failure.SOLUTION: Omecamtiv mecarbil dihydrochloride salt having the following structure. Preferably, the salt shows an x-ray powder diffraction pattern comprising peaks at about 6.6, 14.9, 20.1, 21.4, and 26.8±0.2°2θ using Cu Kα radiation, and is of a crystal form having an endothermic transition at about 230°C to about 240°C as measured by differential scanning calorimetry.SELECTED DRAWING: None 【課題】心不全の治療薬として有用なオメカムチブメカルビルの新規な塩及び多形結晶形状の提供。【解決手段】下記構造を有するオメカムチブメカルビルのジヒドロクロリド塩。前記塩は、ＣｕＫα照射を使用して、約６．６、１４．９、２０．１、２１．４及び２６．８±０．２°２θでのピークを含むＸ線粉末回折パターンを示し、示差走査熱量測定によって測定される場合、約２３０℃〜約２４０℃での吸熱転移を有する結晶形態であることが好ましい。【選択図】なし
