実験手順

To a solution of 4.37 g (25 mmol) of 1-bromo-4-fluorobenzene in 35 ml of ether cooled to -10° was added 15 ml of a 1.6M solution of butyl lithium in hexane in portions while maintaining the temperature below 0°. This mixture was stirred below 0° for 15 min. A solution of 3.63 g (20 mmol) of 4-chloro-6-fluoroquinoline in 20 ml of tetrahydrofuran was added while maintaining the temperature below 0°. The dark solution was stirred at room temperature for 20 min. To the reaction mixture was then added 5 ml of water and 5 g of iodine, and 10 ml of 3N sodium hydroxide. After 10 min of stirring the solid was collected to give 2.8 g of product, mp 130°-133°.
