Procedure

A mixture of 0.5 g of 3-(2-chloropyrid-5-yl-methyl)-2-nitromethylidene-pyrrolidine, 0.3 g of ethyl iodide and 0.27 g of potassium carbonate in 3 ml of dimethylformamide is stirred at room temperature for 18 hours. The reaction mixture is poured onto water and extracted with diethyl ether. The ether phase is dried over magnesium sulfate and concentrated by evaporation in vacuo. The residue is chromatographed on silica gel with ethyl acetate/hexane (2:1). The title compound having a melting point of 129-131° C. (compound 5.5) is obtained.
