3-(4-{[(4-chloro-benzenesulfonyl)-((R)-5,5-difluoro-2-oxo-azepan-3-yl)-amino]-methyl}-phenyl)-propionic acid methyl ester (65 mg, 0.13 mmol) was dissolved in methanol (0.5 ml) and treated with 2 N LiOH in water (0.25 ml, 0.5 mmol) overnight at 40° C. The reaction mixture was distributed between 4 N HCl and ethyl acetate. The organic layer was dried (MgSO4) and concentrated under reduced pressure. The crude product (50 mg) was purified using column chromatography (dichloromethane/methanol 90:10) to yield 45 mg (71%);
