実験手順

Compound 4-3 (3 g, 12.98 mmol) and zinc-copper alloy (7.78 g, 64.9 mmol) were placed in 100 mL of diethyl ether, added dropwise a solution of CCl3COCl (6.97 g, 38.33 mmol) dissolved in 15 mL of DMA with stirring slowly. After the completion of addition, the mixture was stirred at room temperature for 18 hours. To the reaction mixture was poured 100 mL of saturated aqueous solution of sodium bicarbonate, and suction filtrated to remove insolubles, liquid separated, the aqueous phase was extracted with diethyl ether. The organic phases were combined, dried over anhydrous sodium sulfate, suction filtrated to remove the desiccant, and rotary evaporated to remove solvents, the resulting crude Compound 4-4 was used directly in the next reaction.
