Procedure

(S)-3-(4-Cyanophenyl)-2-{[1-(1-cyclohexyl-2-furan-3-yl-1H-benzoimidazol-5-yl)-methanoyl]-amino}-propionic acid ethyl ester from example 10 (0.120 g, 0.235 mmol) was dissolved in a mixture of acetone (5 mL) and water (3 mL). Urea-hydrogen peroxide complex (1.0 mmol, 0.094 g) and potassium carbonate (10 mg) were added and the mixture stirred until completion (HPLC). The reaction mixture was concentrated under reduced pressure, the residue was dissolved in DMSO (1.5 mL) and 5 N NaOH (0.2 mL) was added. After stirring for 30 min at room temperature, TFA (0.5 mL) was added and the product isolated by prep HPLC (18 mg).
