Procedure

{3-Chloro-4-[3,3,3-trifluoro-2-hydroxy-1-methyl-2-(3-methyl-2-oxo-2,3-dihydrobenzooxazol-5-yl)-propyl]-benzoylamino}-acetic acid tert-butyl ester (20 mg, obtained in Example 231) was dissolved in dry dichloromethane (1.0 mL) and trifluoroacetic acid (0.41 mL) was added. The mixture was then allowed to stir at r.t. for 12 hours. The reaction mixture was concentrated in vacuo and the residue was further purified by repeated evaporation from ether (2 times), methanol (2 times) and again dichloromethane (2 times) to give the title compound {3-chloro-4-[3,3,3-trifluoro-2-hydroxy-1-methyl-2-(3-methyl-2-oxo-2,3-dihydrobenzooxazol-5-yl)-propyl]-benzoylamino}-acetic acid as a colorless solid (18 mg). MS (m/e, ISP neg. ion)=485.1 [M−H+].
