Reaction Steps

A solution of (S)-3-[4-carbamoyl-2-(2-quinolin-5-yl-ethoxy)-benzenesulfonylamino]-3-cyano-propionic acid tert-butyl ester (0.13 g, 0.20 mmol) in TFA (2 mL) and CH2Cl2 (20 mL) was stirred for 9 h. Toluene (50 mL) was added and the solvents were removed under vacuum. The residue was lyophilized to yield 100 mg (99%) of (S)-3-[4-carbamoyl-2-(2-quinolin-5-yl-ethoxy)-benzenesulfonylamino]-3-cyano-propionic acid as a pale yellow solid. MS m/z 469.2 (M+1).
