반응 단계

Sodium hydroxide (20.2 g) was added to a water (400 ml) solution of 4-bromo-2-fluorophenol (T-7) (76.4 g), bromobutane (65.8 g) and tetrabutylammonium bromide (TBAB) (6.44 g), and the mixture was heated with stirring at 80° C. for 6 hours under an atmosphere of nitrogen. After the completion of the reaction, the reaction mixture was extracted with heptane, and the organic layer was washed with water and brine, and then dried over anhydrous magnesium sulfate. The solution was concentrated under reduced pressure to leave a black oil. The oil was purified by distillation to give 4-bromo-1-butoxy-2-fluorobenzene (T-8) as a colorless oil (97.5 g) in 98% yield.
