摘要:
The invention also relates to compounds of formula (I), a pharmaceutically acceptable salt, solvate or prodrug thereof: wherein R1 is phenyl or cyclohexyl, either of which is optionally substituted by 1, 2 or 3 halogen atoms, which atoms may be the same or different; R2 is C1-6alkyl or C3-6cycloalkyl; n is 1 or 2; R3 is hydrogen, C1-6alkyl or C3-6cycloalkyl; X is -(C=O)- or -SO2-; R4 is C1-6alkyl, C1-6haloalkyl, C1-6alkoxy, C1-6alkoxyC1-6alkyl, C1-6haloalkoxy, amino, monoC1-6alkylamino or diC1-6alkylamino, or R4 is heterocyclyl or carbocyclyl, either of which is optionally substituted independently by one or more halogen, C1-6alkyl, C1-6haloalkyl, C1-6alkoxy or C1-6haloalkoxy; R5 is phenyl or thienyl, either of which is optionally substituted by 1, 2 or 3 halogen atoms; and y is 0, 1 or 2; wherein when y is 1 or 2, Y is a halogen atom, and wherein when y is 2 the halogen atoms may be the same or different. Also disclosed are use of the compounds in treating diseases and conditions mediated by activation of the NK3 receptor, compositions containing the derivatives and processes for their preparation.
