The present invention concerns amino-benzimidazoles having inhibitory activity on the replication of the respiratory syncytial virus and having the formula (I) their prodrugs, N-oxides, addition salts, quaternary amines, metal complexes and stereochemically isomeric forms wherein Q is Ar1 or C1-6alkyl substituted with one or more substituents selected from trifluoromethyl, C3-7cycloalkyl, Ar2, hydroxy, C1-4alkoxy, C1-4alkylthio, Ar2-oxy-, Ar2-thio-, Ar2(CH2)„oxy, Ar2(CH2)nthio, hydroxycarbonyl, aminocarbonyl, C1-4 alkylcarbonyl, Ar2carbonyl, C1-4alkoxycarbonyl, Ar2(CH2)n carbonyl, aminocarbonyloxy, C1-4 alkylcarbonyloxy, Ar2carbonyloxy, Ar2(CH2)ncarbonyloxy, hydroxy-C2- 4-alkyloxy, C1-4 alkoxycarbonyl(CH2)noxy, monoor di(C1-4alkyl)-aminocarbonyl, mono- or di(C1-4alkyl)aminocarbonyloxy, aminosulfonyl, mono- or di(C1-4alkyl)aminosulfonyl, dioxolanyl optionally substituted with one or two C1-6alkyl radicals, and a heterocycle selected from pyrrolidinyl, pyrrolyl, dihydropyrrolyl, thiazolidinyl, imidazolyl, triazolyl, piperidinyl, homopiperidinyl, piperazinyl, pyridyl and tetrahydropyridyl, which each may optionally be substituted with oxo or C1-6alkyl; G is a direct bond or optionally substituted C1-10alkanediyl R1 is Ar1 or a monocyclic or bicyclic heterocycle; one of R2a and R3a is C1-6alkyl and the other one of R2a and R3a is hydrogen; in case R2a is different from hydrogen then R2b is hydrogen or C1-6alkyl, and R3b is hydrogen; in case R3a is different from hydrogen then R3b is hydrogen or C 1-6alkyl, and R2b is hydrogen; Ar1 is phenyl or substituted phenyl and Ar2 is phenyl or substituted phenyl. It further concerns their preparation and compositions comprising them, as well as their use as a medicine.
