摘要:
A compound of formula (I) ** Formula ** or a stereochemically isomeric form thereof, wherein R 1 is selected from the group consisting of C 1-6 alkyl, (C 3-8 cycloalkyl) C 1-3 alkyl, (alkyloxy C1-3) C1-3 alkyl and C1-3 alkyl substituted with 1, 2 or 3 fluoro substituents; R2 is selected from the group consisting of Cl, CF3, -CN and cyclopropyl; R3 is selected from the group consisting of hydrogen, methyl and CF3; R4 is selected from the group consisting of hydrogen and methyl; or R3 and R4 together with the carbon to which they are attached form a cyclopropyl ring or a carbonyl group; L is selected from the group consisting of (La), (Lb), (Ld), (Lc), (Le), (Lf), (Lh) and (Lg): ** Formula ** (Le) ( Lf) (Lg) (Lh) in which R5a, R5b, R5c and R5d are each independently selected from the group consisting of phenyl; phenyl substituted with 1 or 2 substituents each independently selected from the group consisting of C1-3 alkyloxy and halo; pyridinyl; pyridinyl substituted with 1 or 2 substituents each independently selected from the group consisting of C1-3 alkyl, C1-3 alkyloxy and halo; pyrimidinyl and pyrimidinyl substituted with 1 or 2 substituents each independently selected from the group consisting of C1-3 alkyl, C1-3 alkyloxy and halo; R6e is selected from the group consisting of hydrogen and C1-3 alkyl; R5f, R5g, and R5h are each independently selected from phenyl and phenyl substituted with 1 or 2 fluoro substituents; R6a, R6b and R6c are each independently selected from the group consisting of hydrogen; fluoro; C1-3 alkyl; C1-3 alkyl substituted with 1, 2 or 3 fluoro substituents; C1-3 alkyloxy; C1-3 alkyloxy substituted with 1, 2 or 3 fluoro substituents; and C3-6 cycloalkyl; R6h is C1-3 alkyl; R7a, R8a, R7b, R8b, R7c, R8c, R7d and R8d are each independently selected from the group consisting of hydrogen, halo and methyl; or each R7a and R8a, R7b and R8b, R7c and R8c, and R7d and R8d together with the carbon to which they are attached form a cyclopropyl or carbon
