Methane, dichloromethoxy- → 4-broMo-2-fluoro-5-Methoxy-benzaldehyde

Temperature

0 °C

To a mixture of 2-bromo-4-fluoro-1-methoxybenzene (4.10 g) and titanium tetrachloride (4.4 mL), dichloromethyl methyl ether (3.5 mL) was added under ice cooling, and then the reaction mixture was stirred at 0° C. for 2.5 hours. To the reaction mixture was added chloroform, and the reaction mixture was poured into ice water, and then stirred at room temperature for 1 hour. The organic layer was separated and dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated under reduced pressure. The obtained residue was added hexane and the produced solid was filtered to give the titled compound (1.61 g) as a white solid.
