To a solution of 2-fluoro-6-methoxybenzaldehyde (0.5 g) in tetrahydrofuran (10 mL) was added methyllithium (1.15 mol/L diethyl ether solution, 3.4 mL) at −78° C., and the mixture was stirred at the same temperature for 1 hour. Then the mixture was stirred at room temperature for 30minutes. To the reaction mixture was added a saturated aqueous ammonium chloride solution, and the resulting mixture was extracted with diethyl ether. The extract was washed with water and brine successively, and dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure to give the title compound (0.45 g).
