Reaction Steps
2,3-Dihydroxybenzaldehyde (1.00 g, 7.24 mmol), potassium carbonate (1.00 g, 7.24 mmol) and iodomethane (0.59 ml, 1.34 g, 9.4 mmol) in dry DMF (10 ml) were stirred at ambient temperature for 19 h. The reaction mixture was cooled, poured into water and extracted with ethyl acetate. The ethyl acetate layer was extracted with 1N aqueous sodium hydroxide (3×). The basic extracts were combined and acidified by addition of 3N hydrochloric acid, then extracted with ethyl acetate. The ethyl acetate layer was washed with water (4×), brine and dried over MgSO4. After filtration, the solvent was removed in vacuo to yield 3-hydroxy-2-methoxy-benzaldehyde (0.68 g, 62%) as a yellowish-tan solid.
