실험 절차

To a stirring solution of 3-bromo-6-methoxybenzene-1,2-diol (500 mg, 2.27 mmol) in acetone (40 mL) at 0° C. was added potassium carbonate (313 mg, 2.27 mmol) and methoxymethyl chloride (183 mg, 2.27 mmol) and the resultant reaction mixture was stirred at RT for 2 h. The reaction mixture was filtered and filtrate was concentrated under reduced pressure. Purification of the residue by column chromatography (silica gel, 0-8% ethyl acetate in pet ether) afforded 3-Bromo-6-methoxy-2-(methoxymethoxy)phenol as a liquid (230 mg, 38%).
