Reaction Steps
To a stirring solution of benzene-1,2,3-triol (2 g, 15.87 mmol) in acetone was added potassium bicarbonate (1.9 g, 19.04 mmol) and methyl iodide (3.3 g, 23.8 mmol) and the resultant reaction mixture was heated to reflux for 16 h. The reaction mixture was cooled to RT, filtered through celite and the filtrate was concentrated under reduced pressure. The residue was diluted with ether, solid separated out was filtered and the filtrate was concentrated under reduced pressure to afford the crude product. The crude product was purified by flash column chromatography (silica gel, 0-15% ethyl acetate in pet ether) to afford 2-Methoxybenzene-1,3-diol as a solid (600 mg, 27%).
