Reaction Steps
A mixture comprising 20 g of N-benzyloxycarbonyl-3-hydroxy-4-methoxybenzylamine, 17.43 g of ethyl bromoacetate, 14.43 g of potassium carbonate and 200 ml of 2-butanone, was refluxed under heating with stirring overnight. The mixture was cooled to room temperature. Then, inorganic substances were filtered off, and the filtrate was distilled under reduced pressure. The obtained residue was extracted with chloroform, and the organic layer was washed with water and a saturated sodium chloride aqueous solution and then dried over anhydrous sodium sulfate. Then, the solvent was distilled off. The obtained residue was crystallized from diethyl ether/n-hexane to obtain 17.83 g of the above-identified compound as white crystals.
