    • The invention relates to compounds of formula ( I ) wherein R 1 /R 1' are independently from each other hydrogen, halogen, lower alkoxy or cyano; R 2 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, CH 2 -O-lower alkyl, cycloalkyl, NRR'or is -O-(CH 2 ) o -phenyl optionally substituted by halogen, or is -(CH 2 ) o -phenyl optionally substituted by one, two or three substituents, selected from halogen, -(CH 2 ) o -cyano, lower alkyl, lower alkyl substituted by halogen, lower alkyl substituted by hydroxy, C(O)H, -CH 2 -NH 2 -, -CH 2 -NH-C(O)O-lower alkyl, -CH 2 -NH-C(O)-lower alkyl, -CH 2 -NH-lower alkyl, -CH 2 -NH-S(O) 2 -lower alkyl, lower alkoxy or by lower alkoxy substituted by halogen, or is -(CH 2 ) o -cycloalkyl, or is -(CH 2 ) o -heterocycloalkyl which is optionally substituted by halogen, CF 3 , lower alkyl, -CH 2 CN, -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; R 3 may occur once or twice and is lower alkyl; A is Formula a), b), c), d), e), f), h), i), j) and Formula k); R 2' 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, R 2 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.
