A compound of formula (I) in free form or in pharmaceutically acceptable salt form wherein, R 1 is selected from C 1 -C 3 alkyl and halogen; R 2 is selected from NHSO 2 (CH 2 ) n R 3 or SO 2 NR 5 R 6 ; n is 0 or 1; R 3 is selected from phenyl optionally substituted once or more than once with R 4 ; C 3 -C 6 cycloalkyl optionally substituted with hydroxyl; a fused bicyclic aromatic ring system; R 4 is independently selected from halogen, C 1 -C 3 alkoxy, cyano, C 1 -C 3 alkyl, hydroxyl, haloC 1 -C 3 alkyl, NHC(O)CH 3 , haloC 1 -C 3 alkoxy, SO 2 NH(CH); and/or two R 4 at adjacent carbon atoms form a 5- or 6-membered heterocyclic non-aromatic ring comprising at least one heteroatom selected from N, O, or S said heterocyclic ring being fused to the phenyl ring and being optionally substituted with C(O)CH 3 ; R 5 is selected from H, C 1 -C 3 alkyl; R 6 is selected from a C 3 -C 6 cycloalkyl optionally substituted once or more than once with R 7 ; phenyl optionally substituted once or more than once with halogen; C 1 -C 6 alkyl optionally substituted with hydroxyl; 4- to 6-membered heterocyclic non-aromatic ring comprising at least one heteroatom selected from N, O or S optionally substituted once or more than once with oxo; benzyl; R 7 is independently selected from hydroxyl, haloC 1 -C 3 alkyl, halogen, C 1 -C 3 alkyl, C(O)OH, hydroxyC 1 -C 3 alkyl; or R 5 and R 6 together with the N atom to which they are attached form a 4-, 5- or 6-membered heterocyclic non-aromatic ring optionally comprising one additional heteroatom selected from N, O or S, said ring being optionally substituted once or more than once with R 8 ; a 6- to 8-membered saturated bicyclic ring system; R 8 is independently selected from halogen; hydroxyC 1 -C 3 alkyl; C(O)NH 2 ; hydroxyl; haloC 1 -C 3 alkyl optionally substituted with hydroxyl; phenoxy; SO 2 C 1 -C 3 alkyl. R 1 is selected from C 1 -C 3 alkyl and halogen; R 2 is selected from NHSO 2 (CH 2 ) n R 3 or SO 2 NR 5 R 6 ; n is 0 or 1; R 3 is selected from phenyl optionally substituted once or more than once with R 4 ; C 3 -C 6 cycloalkyl optionally substituted with hydroxyl; a fused bicyclic aromatic ring system; R 4 is independently selected from halogen, C 1 -C 3 alkoxy, cyano, C 1 -C 3 alkyl, hydroxyl, haloC 1 -C 3 alkyl, NHC(O)CH 3 , haloC 1 -C 3 alkoxy, SO 2 NH(CH); and/or two R 4 at adjacent carbon atoms form a 5- or 6-membered heterocyclic non-aromatic ring comprising at least one heteroatom selected from N, O, or S said heterocyclic ring being fused to the phenyl ring and being optionally substituted with C(O)CH 3 ; R 5 is selected from H, C 1 -C 3 alkyl; R 6 is selected from a C 3 -C 6 cycloalkyl optionally substituted once or more than once with R 7 ; phenyl optionally substituted once or more than once with halogen; C 1 -C 6 alkyl optionally substituted with hydroxyl; 4- to 6-membered heterocyclic non-aromatic ring comprising at least one heteroatom selected from N, O or S optionally substituted once or more than once with oxo; benzyl; R 7 is independently selected from hydroxyl, haloC 1 -C 3 alkyl, halogen, C 1 -C 3 alkyl, C(O)OH, hydroxyC 1 -C 3 alkyl; or R 5 and R 6 together with the N atom to which they are attached form a 4-, 5- or 6-membered heterocyclic non-aromatic ring optionally comprising one additional heteroatom selected from N, O or S, said ring being optionally substituted once or more than once with R 8 ; a 6- to 8-membered saturated bicyclic ring system; R 8 is independently selected from halogen; hydroxyC 1 -C 3 alkyl; C(O)NH 2 ; hydroxyl; haloC 1 -C 3 alkyl optionally substituted with hydroxyl; phenoxy; SO 2 C 1 -C 3 alkyl. <EOS>
