Procedure
To a solution of 3-[4-carbamoyl-2-(2-naphthalen-1-yl-ethoxy)-benzenesulfonylamino]-4-oxo-butyric acid tert-butyl ester (0.18 g, 0.34 mmol) in dichloromethane (10 mL) and water (0.1 mL) was added trifluoroacetic acid (1 mL). The reaction was stirred for 2 hours at room temperature. The reaction was then concentrated under reduced pressure to yield a colorless oil. The residue was purified by HPLC using a gradient of 10% to 50% acetonitrile containing 0.1% TFA and water at containing 0.1% TFA over 140 minutes to yield 3-[4-carbamoyl-2-(2-naphthalen-1-yl-ethoxy)-benzenesulfonylamino]-4-oxo-butyric acid as a lyophilized as a white solid (0.045 g, 28%). MS(APCI) m/z 471.0 (M+1).
