Versuchsvorschrift
Alternatively, a mixture of 2-nitroimidazole, anhydrous potassium carbonate, and (S)-(+)-epichlorohydrin is refluxed for 10 minutes then filtered while hot. The filtrate is concentrated and cooled to give a solid. Crystallization from ethanol and further processing gives the product.
