Reaction Steps

To a solution of 3-(4-tert-Butoxycarbonylmethoxy-phenyl)-propionic acid methyl ester (2.70 g, 9.17 mmol) in THF (80 ml) is added 0.2N lithium hydroxide (45.9 ml, 9.17 mmol) at 0° C. and the reaction mixture is stirred at 0° C. for 4.5 hours. 1M HCl (15 ml) is added and the product is extracted using EtOAc (×3). The organic phase is dried (Na2SO4) and concentrated in vacuo to yield a white solid. Flash chromatography (SiO2, 10% EtOAc in CH2Cl2, then 20% EtOAc in CH2Cl2) yields 3-(4-tert-Butoxycarbonylmethoxy-phenyl)-propionic acid as a white solid.
