Inside of a 100 ml volume glass three-neck flask equipped with a 50 ml volume glass dropping funnel, temperature resistor and septum rubber was sufficiently replaced with nitrogen. Into the flask, 5 g (29.8 mmol) of pentafluorobenzene and 30 ml of diethyl ether were charged, of which solution was cooled to -65° C. Thereafter, 12.3 g (29.8 mmol) of 15.5 wt. % pentane solution of tert-butyllithium charged into the dropping funnel were added dropwise while making the inner temperature not to exceed -55° C. After the completion of dropwise addition, the reaction mixture was kept at a temperature of -65°~-55° C. with stirring to give pentafluorophenyllithium.
