实验步骤: A solution of 2-chloropropionyl chloride (49 ml) in dichloromethane (50 ml) was added to a mixture of anhydrous aluminium trichloride (55.5 g) in dichloromethane (120 ml). The mixture was stirred for 10 minutes at room temperature and then a solution of fluorobenzene (39.5 ml) in dichloromethane (30 ml) was added dropwise. The resulting mixture was stirred for one hour, allowed to stand for 16 hours and then poured on to an icehydrochloric acid mixture. The two phase mixture was vigorously stirred at room temperature for 11/2 hours, separated and the aqueous layer washed with dichloromethane (2×50 ml). The combined organic extracts were then washed with aqueous sodium hydroxide (3N, 2×100 ml), water (1×100 ml) and brine (1×100 ml), dried (MgSO4) and evaporated under reduced pressure to afford 2-chloro-1-(4-fluorophenyl)-1-propanone, 71.3 g. The resulting mixture was stirred for one hour to stand for 16 hours poured on to an icehydrochloric acid mixture The two phase mixture was vigorously stirred at room temperature for 11/2 hours separated the aqueous layer washed with dichloromethane (2×50 ml) The combined organic extracts were then washed with aqueous sodium hydroxide (3N, 2×100 ml), water (1×100 ml) and brine (1×100 ml) dried (MgSO4) evaporated under reduced pressure

实验步骤: Sodium hydride (50% oil dispersion, 3.5 g) was added with caution to a cooled solution of diethyl malonate (11.85 ml) in dimethylformamide (10 ml). The reaction mixture was stirred at room temperature for 30 minutes before a solution of 2-chloro-1-(4-fluorophenyl)-1-propanone (12.13 g) in dimethylformamide (50 ml) was added in small aliquots. The resulting reaction mixture was stirred for 2 hours at room temperature and then water (35 ml) was added. The mixture was extracted with petroleum ether (b.p. 40°-60° C.) (3×50 ml) and the combined organic extracts were evaporated under reduced pressure to afford ethyl 2-ethoxycarbonyl-3-(4-fluorobenzoyl)butanoate (15.92 g). was added in small aliquots The resulting reaction mixture The mixture was extracted with petroleum ether (b.p. 40°-60° C.) (3×50 ml) the combined organic extracts were evaporated under reduced pressure
