Nitrocyclopropane is prepared by reacting 3-chloro-1-nitropropane with an amine which has a polar center in addition to an amino function in the presence of a polar, aprotic solvent. For example, the reaction of 3-chloro-1-nitropropane with ethylene diamine in the presence of dimethyl sulfoxide produces nitrocyclopropane in high yield.
