The present invention relates to triazolo pyridines of formula (II) and their use as modulators of -secretase. In particular, the present invention relates to compounds which interfere with -secretase and/or its substrate and therefore modulate the formation of Aβ peptides. Accordingly these compounds can be used for the treatment of Aβ-related pathologies, e.g. Alzheimer's disease.
Reactions of benzotriazoles with diethyl ethoxymethylenemalonate; ethylation and michael addition. Comparison with other esters and<i>N</i>-heterocycles
Benzotriazole and its 5-methyl-and 5-nitro derivatives react with diethylethoxymethylenemalonate by ethylation at each of the ring N-atoms and through Michael addition, to give the isomeric esters ethyl (E/Z) 3-[5(6)-R-benzotriazol-1-yl]propenoates. Benzotriazole and its 5-nitro derivative react similarly with ethyl acetoacetate but N-ethyl derivatives are obtained in lower yields. Other 1,2,3-triazoles

The present invention relates to triazolo pyridines of formula (II) and their use as modulators of #-secretase. In particular, the present invention relates to compounds which interfere with #-secretase and/or its substrate and therefore modulate the formation of Aβ peptides. Accordingly these compounds can be used for the treatment of Aβ-related pathologies, e.g. Alzheimer's disease.

The purpose of the present invention is to provide a nonaqueous electrolyte that contains acetonitrile having an excellent balance between viscosity and the dielectric constant and a fluorine-containing inorganic lithium salt, wherein the generation of complex cations comprising a transition metal and acetonitrile is suppressed, excellent load characteristics are exhibited, and increases in internal resistance upon repeated charge/discharge cycles are suppressed; a further purpose of the present invention is to provide a nonaqueous secondary battery. The present invention relates to a nonaqueous electrolyte which contains: a nonaqueous solvent comprising acetonitrile; a fluorine-containing inorganic lithium salt; and a specific nitrogenous cyclic compound typified by benzotriazole.
