実験手順

To a mixture of fluorobenzene (37.3 g) and adipic acid monoethyl ester chloride (18.0 g) was added gradually aluminum chloride (26.6 g) with stirring under ice-cooling, and the resulting mixture was stirred at room temperature for 2 hours. The reaction mixture was poured into ice water (500 ml) and extracted with diethyl ether (200 ml×2). The organic layer was washed with a 10% aqueous solution of sodium hydrogen carbonate (200 ml), dried over anhydrous magnesium sulfate, and concentrated to give ethyl 6-(4-fluorophenyl)-6-oxohexanoate as an oil (14.1 g, 57%).
