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; (C3-8 cycloalkyl) C1-3 alkyl; (C1-3 alkyloxy) 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; L is selected from the group consisting of (La), (Lb), (Ld), (Lc), (Le), (Lf), (Lh) and (Lg): ** Formula ** in which ma , mb, and mc are each independently selected from the group consisting of 0 and 1; me and mg are each independently selected from the group consisting of 1 and 2; na, nb, nc, nd, ne, nf, ng and nh are each independently selected from the group consisting of 0, 1 and 2; R5a, R5b, R5c, R5d, R5e, R5f, R5g and R5h are each independently selected from the group consisting of halo; C1-3 alkyl; C1-3 alkyl substituted with 1, 2 or 3 fluoro substituents; C1-3 alkyloxy; and C1-3 alkyloxy substituted with 1, 2 or 3 fluoro substituents; R6a is selected from the group consisting of hydrogen; halo; C1-3 alkyl; C1-3 alkyl substituted with 1, 2 or 3 fluoro substituents; C1-3 alkyloxy; and C1-3 alkyloxy substituted with 1, 2 or 3 fluoro substituents; R6c is selected from the group consisting of hydrogen; halo; 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 cyclopropyl; R7a, R8a, R7b and R8b are each independently selected from the group consisting of hydrogen, fluoro and methyl; or R7a and R8a, and R7b and R8b together with the carbon to which they are attached form a cyclopropyl or a carbonyl group; in which each halo is selected from the group consisting of fluoro, chloro, bromo and iodo; with the pr
