Procedure
15.0 g of 1-(1-ethoxy-1-propoxy)methyl-2-nitroiminoimidazolidine, 11.6 g of anhydrous potassium carbonate, 11.3 g of 2-chloro-5-chloromethylpyridine and 60 ml of dimethyl sulfoxide were agitated at 75° C. for 1 hour. The reaction mixture was poured into water, and extracted with ethyl acetate. After washing with water, the extract was dried with anhydrous sodium sulfate, after which the solvent was distilled off under reduced pressure. The resultant oily residue was purified by column chromatography [silica gel, eluant hexane/ethyl acetate (1:2)] to give 4.7 g of 1-(1-ethoxy-1-propoxy)methyl-2-nitroimino-3-(2-chloropyridin-5-ylmethyl)imidazolidine.
