    • The invention relates to compounds of formula (I). Hetaryl I is a five or six membered heteroaryl group, containing 1 to 3 heteroatoms, selected from O, S or N; hetaryl II is a five or six membered heteroaryl group, containing 1 to 3 heteroatoms, selected from O, S or N, or is a two membered ring system containing 1 to 4 heteroatoms selected from S, O or N, wherein at least one ring is aromatic in nature; R1 is lower alkyl, lower alkoxy, lower alkyl substituted by halogen, or halogen; R2 is halogen, lower alkyl, lower alkoxy, hydroxy, lower alkyl substituted by halogen, lower alkyl substituted by hydroxy or benzo[1,3]dioxolyl, or is -(CHR)p-phenyl, optionally substituted by halogen, lower alkyl, lower alkoxy, S(O)2-lower alkyl, cyano, nitro, lower alkoxy substituted by halogen, dimethylamino, -(CH2)P-NHC(O)O-Iower alkyl, or lower alkyl substituted by halogen, and R is hydrogen, halogen, hydroxy or lower alkoxy, or is cycloalkenyl or cycloalkyl, optionally substituted by hydroxy or lower alkyl substituted by halogen, or is a five or six membered heteroaryl group, containing 1 to 3 heteroatoms, selected from O, S or N, which is optionally substituted by halogen, lower alkyl, lower alkoxy or dimethylamino, or is O-phenyl, optionally substituted by halogen, or is heterocycloalkyl, optionally substituted by halogen, hydroxy, lower alkyl substituted by halogen or C(O)O-lower alkyl; R3 is hydrogen, lower alkyl, cyano or phenyl; R4 is lower alkoxy, lower alkyl or halogen; p is 0 or 1; n is 0, 1 or 2; if n is 2 then R4 may be the same or different; m is 0, 1 or 2; if m is 2 then R1 may be the same or different; o is 0, 1, 2 or 3, if o is 2 or 3 then R2 may be the same or different; or to pharmaceutically active acid addition salts thereof. The compounds of formula (I) are modulators for amyloid beta and thus, they may be useful for the treatment or prevention of a disease associated with the deposition of ß-amyloid in the brain, in particular Alzheimer's disease, and other diseases such as cerebral amyloid angiopathy, hereditary cerebral hemorrhage with amyloidosis, Dutch-type (HCHWA-D), multi-infarct dementia, dementia pugilistica and Down syndrome.
