A series of novel quinoxaline derivatives were synthesized and evaluated for their inhibitory activity against c-Met kinase enzyme. Most of the tested compounds exhibited potent inhibitory activity. All the synthesized quinoxaline compounds were further e

A practical method for radiofluorination of anilines with [18F]fluoride via N-arylsydnone intermediates is described. These precursors are stable, easy to handle and facilitate direct and regioselective 18F-labeling to prepare [

Since previous routes to the title compounds (1) have proved unsatisfactory as general methods, a simple new synthesis has been devised.N-Cyanomethyl-o-nitroanilines (5) are cyclised in basic media, giving 2-cyanobenzimidazole N-oxides (12) in good yield.Hydrolysis of these products with hydrochloric acid gives, directly, the title compounds as their hydrochloride salts (13), which may be isolated and purified, and which give the free N-oxides (1) by treatment with aqueous ammonia followed by evaporation. o-Nitrophenylglycine esters (4) may satisfactorily replace the nitriles (5) in certain cases.A modification of this kind in the related nitropyridylglycine series leads to 3H-imidazolpyridine 1-oxide (20).
