The invention relates to compounds of formula ( I ) wherein R1/R1' are independently from each other hydrogen, halogen, lower alkoxy or cyano; R2 is lower alkyl, halogen, lower alkoxy, lower alkyl substituted by halogen, lower alkoxy substituted by halogen, lower alkyl substituted by OR, =0, -C(O)O-lower alkyl, -C(O)NH-lower alkyl, cyano, CH2-O-lower alkyl, cycloalkyl, NRR'or is -O-(CH2)o-phenyl optionally substituted by halogen, or is -(CH2)o-phenyl optionally substituted by one, two or three substituents, selected from halogen, -(CH2)o-cyano, lower alkyl, lower alkyl substituted by halogen, lower alkyl substituted by hydroxy, C(O)H, -CH2-NH2-, -CH2-NH-C(O)O-lower alkyl, -CH2-NH-C(O)-lower alkyl, -CH2-NH-lower alkyl, -CH2-NH-S(O)2-lower alkyl, lower alkoxy or by lower alkoxy substituted by halogen, or is -(CH2)o-cycloalkyl, or is -(CH2)o-heterocycloalkyl which is optionally substituted by halogen, CF3, lower alkyl, -CH2CN, -C(O)-lower alkyl, -C(O)O-lower alkyl or S(O)2-lower alkyl, or is heteroaryl selected from the group consisting of furanyl, pyrazinyl, pyridinyl, benzooxazolyl or benzoimidazolyl which are optionally substituted by lower alkyl, or is 4-methyl-3,4-dihydro-2H-benzo[l,4]oxazine R and R' are independently from each other hydrogen or lower alkyl, and o is 0 or 1; R3 may occur once or twice and is lower alkyl; A is Formula a), b), c), d), e), f), h), i), j) and Formula k); R2' is hydrogen, lower alkyl, lower alkyl substituted by halogen, C(O)-lower alkyl, S(O)2-lower alkyl or phenyl optionally substituted by halogen; hetaryl is a 5 or 6 membered N, S or O-containing heteroaryl group; n is O, 1, 2 or 3; if n is 2 or 3, R2 may be the same or not; or to pharmaceutically active acid addition salts thereof. The present 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 β-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.
