The present invention provides compounds of formula (I) including stereoisomers, prodrugs and pharmaceutically acceptable salts or solvates thereof, wherein R is aryl or heteroaryl, each of which may be substituted by 1 to 4 groups selected from: halogen, C1-C6 alkyl, C1-C6 alkoxy, halo C1-C6 alkyl, C2-C6 alkenyl, C2-C6 alkynyl, halo C1-C6 alkoxy, -C(O)R5, nitro, -NR6R7, cyano, and a group R8; R1 is hydrogen, C1-C6 alkyl, C2-C6 alkenyl, C2-C6 alkynyl, halo C1-C6 alkyl, halo C1-C6 alkoxy, halogen, NR6R7 or cyano; R2 is hydrogen, C3-C7 cycloalkyl, or a group R9; R3 is C3-C7 cycloalkyl, or a group R9; or R2 and R3 together with N form a 5-14 membered heterocycle, which may be substituted 1 to 3 R10 groups; R4 is hydrogen, C1-C6 alkyl, halogen or halo C1-C6 alkyl; R5 is a C1-C4 alkyl, -OR6 or NR6R7; R6 is hydrogen or C1-C6 alkyl; R7 is hydrogen or C1-C6 alkyl; R8 is a 5-6 membered heterocycle, which may be saturated or may contain one to three double bonds, and which may be substituted by 1 or more R11 groups; R9 is a C1-C6 alkyl that may be substituted by one or more groups selected from: C3-C7 cycloalkyl, C1-C6 alkoxy, halo C1-C6 alkoxy, hydroxy, halo C1-C6 alkyl; R10 is a group R8, C3-C7 cycloalkyl, C1-C6 alkyl, C1-C6 alkoxy, halo C1-C6 alkyl, C2-C6 alkenyl, C2-C6 alkynyl, halo C1-C6 alkoxy, hydroxy, halogen, nitro, cyano, C(O)NR6R7, phenyl which may be substituted by 1 to 4 R11 groups; R11 is C3-C7 cycloalkyl, C1-C6 alkyl, C1-C6 alkoxy, halo C1-C6 alkyl, C2-C6 alkenyl, C2-C6 alkynyl, halo C1-C6 alkoxy, hydroxy, halogen, nitro, cyano, or C(O)NR6R7; X is carbon or nitrogen; n is 1 or 2; to processes for their preparation, to pharmaceutical compositions containing them and to their use in the treatment of conditions mediated by corticotropin-releasing factor (CRF). |
