Procedure

4-(4-Benzyloxycarbonylmethyl-phenoxy)-butyric acid methyl ester (1.4 g, 4.09 mmol) was dissolved in EtOAc (60 ml). Pd/carbon (100 mg) was added and the reaction stirred under a hydrogen atmosphere (balloon) for 16 h at room temperature. The reaction mixture was filtered through a pad of celite and the pad washed with EtOAc. The filtrate was evaporated to dryness to give a white solid (1.03 g, 100% yield). LCMS purity 93%, m/z 253 [M++H]+.
