実験手順

71.8 g. (0.288 moles) of α-(3,5-dichlorophenoxy) butyric acid and 75 ml. of benzene are placed in a 500 ml. flask to which a dropping funnel with dry-ice condenser is attached. The slurry is stirred and the 0.2 ml. dimethyl formamide is added. The mixture is heated to 35° C. and 10 g. of phosgene is condensed into the mixture to initiate reaction. The start of the reaction is evidenced by HCl evolution and foaming. 26.0 g. more phosgene is added in 5 gm. increments. At the conclusion of the reaction (HCl evolution ceasing), the reaction mixture is evaporated leaving a residual liquid α-(3,5-dichlorophenoxy) butyryl chloride 77.6 g., ND20 = 1.5345
