To 3.5 g (15 mmol) of 3-[2-(2-nitro-1H-imidazol-1-yl)ethyl-2-oxazolidinone was added 30 ml of 31% HBr/acetic acid and the mixture was stirred for 18 hours at 20°-25° C. The mixture was diluted with ether and methanol and the resulting solid was collected. Recrystallization from ethanol/water gave 3.0 g of the desired product, N-(2-bromoethyl)-2-nitro-1H-imidazole-1-ethanamine, monohydrobromide (54%); mp 103°-104° C.
