Versuchsvorschrift

According to the General Reaction Scheme, N-(2,3-epoxypropyl)phthalimide (1) is reacted with 2-nitro-imidazole (2) to obtain 2-[2-Hydroxy-2-(2-nitro-1H-imidazol-1-yl)ethyl]-1H-isoindole-1,3(2H)-dione (3). This product is then reacted with N-hydroxyphthalimide, preferably in the presence of a tertiary amine such as triphenylphosphine, to obtain the intermediate of Formula II, 2-{2-(1,3-dioxoisoindolin-2-yl)-1-[(2-nitroimidazolyl)methyl]ethoxy}isoindoline-1,3-dione (4). This intermediate is then reacted with hydrazine to obtain 1-[3-amino-2-(aminooxy)propyl]-2-nitro-1H-imidazole dihydrochloride (5), which is then reacted with the compound of Formula III to yield the compound of Formula I. A preferred compound of Formula III is 3-chloro-3-methyl-2-nitrosobutane, which, when used contacted with 1-[3-amino-2-(aminooxy)propyl]-2-nitro-1H-imidazole dihydrochloride (5), yields 3,3,9,9-tetramethyl-6-[(2-nitro-1H-imidazol-1-yl)methyl]-5-oxa-4,8-diazaundecane-2,10-dione dioxime (7).
