. 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.

Copper-Catalyzed Direct Syntheses of Phenoxypyrimidines from Chloropyrimidines and Arylboronic Acids: A Cascade Avenue and Unconventional Substrate Pairs
or their salts. In contrast to the general trend of delivering Suzuki–Miyaura cross-coupling products in reactions between aryl or alky halides and arylboronic acids, the substrate pairs used herein (chloropyrimidines and arylboronic acids) led to C–O bond formation under the reaction conditions. In total, 25 phenoxypyrimidines were successfully synthesized using the described protocol, 6 of which
