, (2011/08/04)
The present invention is concerned with novel substituted bicyclic triazole derivatives of Formula (I) wherein Het1, R1, R2, A1, A2, A3, A4, L1, and L2 have the meaning defined in the claims. The compounds according to the present invention are useful as gamma secretase modulators. The invention further relates to processes for preparing such novel compounds, pharmaceutical compositions comprising said compounds as an active ingredient as well as the use of said compounds as a medicament.

The invention relates to compounds of formula wherein R1, R1′, R2, R3, n, A, and hetaryl are defined herein 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.
