Reaction Steps

0.5 g of 1-(6-chloro-3-pyridylmethyl)-2-nitromethyleneimidazolidine, 0.19 g of 37% formaldehyde aqueous solution and 0.22 g of allylmercaptan were added to 10 ml of ethanol, and were reacted under reflux for 2 hours. After completing the reaction, ethanol was distilled off under reduced pressure, and a small amount of ethyl acetate was added to the residue thus obtained to filter the insoluble materials out, thus obtaining 0.33 g of the aimed product (Compound No. 3) having a melting point of from 134.0° to 135.0° C.
