Novel potassium channel inhibitors

A compound of formula (I)

• Wherein
• R1 is selected from hydrogen and C1-6 alkyl;
• R2-R3 are independently a group selected from hydrogen and C1-6 alkyl;
• or R2 and R3 taken together with the carbon atom to which they are linked form a C3-4 cycloalkyl;
• R4-R6 are independently a group selected from hydrogen, halogen, and C1-4 alkyl;
• R7 is selected from the group consisting of hydrogen and C1-4 alkyl,
• R8 is selected from the group consisting of C1-6 alkyl, C1-6 alkyl substituted with one OH, and C1-6 alkyl substituted with one OC1-3 alkyl,
• or R7 and R8 taken together with the carbon atom to which they are linked form a C3-4 cycloalkyl;
• R9-R13 are independently a group selected from hydrogen, halogen, C1-6 alkyl substituted with at least one halogen, C1-6 alkoxy, C1-6 alkoxy substituted with at least one halogen, C1-6 alkylthio, and cyano;
• R14 is selected from H, C1-6 alkyl, or C1-6 alkoxy;
• R15 is selected from H, C1-6 alkyl, C1-6 alkyl substituted with at least one halogen, C1-6 alkoxy, C1-6 alkoxy substituted with at least one a halogen, or C3-4 cycloalkyl;
• or R14 and R15 taken together with the nitrogen atom to which they are linked form a 4-6 membered non-aromatic heterocycle containing 1-2 nitrogen atoms, optionally 1 oxygen atom, and optionally 1 sulphur atom, optionally substituted with at least one group selected from halogen, C1-6 alkyl, C1-6 alkyl substituted with at least one halogen, C1-6 alkoxy, C1-6 alkoxy substituted with at least one halogen;
• or
• a pharmaceutically acceptable salt thereof.
