The crude benzyl 2-(3-(benzyloxy)phenyl)acetate was dissolved in a mixture of MeOH (20 mL) and THF (50 mL). To this solution was added 40 mL of 1N NaOH (40 mmol). The reaction mixture was stirred at room temperature for 2 h. The organic solvent was removed in vacuo. The remaining aqueous solution was extracted with diethyl ether (2×50 mL). The aqueous solution was then acidified with 1N HCl (50 mL) and the title compound precipitated. The solid was collected by filtration (4.35 g, 90% two steps). MS (ESI+) m/z 265 (M+Na)+.
