Reaction Steps

To a stirring solution of 3-bromo-6-methoxy-2-(methoxymethoxy)phenol (700 mg, 2.64 mmol) in dimethylformamide (15 mL) was added potassium carbonate (729 mg, 5.28 mmol), cooled to −45° C. and chlorodifluoromethane gas was passed for 10 min and the resultant reaction mixture was heated to 80° C. for 2 h. The reaction mixture was quenched with ice-cold water and extracted with ethyl acetate (3×). The combined ethyl acetate layers were dried over sodium sulphate and concentrated under reduced pressure. Purification of the residue by flash column chromatography (silica gel, 0-5% ethyl acetate in pet ether) afforded 1-Bromo-3-(difluoromethoxy)-4-methoxy-2-(methoxymethoxy)benzene as a liquid (250 mg, 30%).
