Participants

Reaction Steps

First, 2.00 g of N-(4-chloro-2-fluoro-5-propargyloxyphenyl)-2-chloroacetamide, 4.50 g of triphenylphosphine and 5 ml of carbon tetrachloride were dissolved in 45 ml of 1,2-dichloroethane, and then the reflux under heat was continued for 2 hr. After letting the solution stand to cool the same, the solvent was distilled out under reduced pressure, and then the residue was refined by silica gel column chromatography (effluent: ethyl acetate/n-hexane (v/v)=6/4) to obtain 1.43 g of N-(4-chloro-2-fluoro-5-propargyloxyphenyl)-2-chloroacetimidoylchloride. The boiling point was 144°-146° C./0.4 mm Hg.
