Patent ID: 8691849

Claim:
A compound having the formula (I) or a stereochemically isomeric form thereof, wherein R 1 is C 1-6 alkyl; or C 1-3 alkyl substituted with C 3-7 cycloalkyl, halo, phenyl, or phenyl substituted with halo, trifluoromethyl or trifluoromethoxy; R 2 is halo, trifluoromethyl, C 1-3 alkyl or cyclopropyl; X is a covalent bond, O, NR 3 , NR 3 —CH 2 or O—CH 2 ; R 3 is hydrogen or C 1-3 3alkyl; and Ar is unsubstituted phenyl; or phenyl substituted with n radicals R 4 ; wherein n is 1, 2 or 3; wherein each R 4 is independently selected from the group consisting of halo, C 1-3 alkyl, hydroxyC 1-3 alkyl, polyhaloC 1-3 alkyl, cyano, hydroxyl, amino, carboxyl, C 1-3 alkyloxyC 1-3 alkyl, C 1-3 alkyloxy, polyhaloC 1-3 alkyloxy, C 1-3 alkylcarbonyl, mono- and di(C 1-3 alkyl)amino, and morpholinyl; or wherein two vicinal R 4 radicals taken together form a bivalent radical of formula —N═CH—NH— (a), or —CH═CH—NH— (b), or —O—CH 2 —CH 2 —NH— (c); or a pharmaceutically acceptable addition salt or a solvate thereof.
