Reaction Steps

1.00 g of 4-chloro-3-[(2,2-dichlorocyclopropyl)methoxy]phenyl chloroformate was dissolved in 20 ml of diethyl ether and, to the solution, there were added 0.32 g of thiazolidine and 0.37 g of triethylamine. The mixture was stirred at 0° to -5° C. for an hour and then washed with water. The ether was distilled off from the ether layer and the oily residue was purified by silica gel column chromatography to give 1.02 g of 4-chloro-3-[(2,2-dichlorocyclopropyl)methoxy]phenyl 3-thiazolidinecarboxylate [Compound (7)], which had the melting point of 74°-79.5° C.
