Reaction Steps
The whole of the crude methyl 4-acetoxymethyl-2-methoxybenzoate thus obtained was dissolved in 100 ml of methanol, and 9.6 ml (4.9 mmol) of a 0.51 M sodium methoxide solution in methanol were added to the solution. The resulting mixture was then stirred for 1 hour. At the end of this time, 0.6 ml of acetic acid were added, to terminate the reaction, and then the reaction mixture was freed from the solvent by distillation under reduced pressure . The resulting residue was mixed with water, and the resulting aqueous solution was extracted with a mixture of ethyl acetate and hexane. The extract was washed with a saturated aqueous solution of sodium hydrogencarbonate, with water and with a saturated aqueous solution of sodium chloride, in that order, after which it was dried over anhydrous sodium sulfate. The solvent was removed by distillation under reduced pressure, and the resulting residue was purified by column chromatography through 250 g of silica gel, using a 2:1 by volume mixture of hexane and ethyl acetate as the eluent, to give 4.39 g of the title compound as an oily substance in a 53% yield (total yield of three steps).
