Versuchsvorschrift

Sodium hydroxide solution (0.24 mL, 2M, 0.48 mmol) was added to a solution of (S)-3-[(5-chloro-1H-pyrrolo[2,3-c]pyridine-2-carbonyl)amino]-(R)-2-hydroxy-4-phenylbutyric acid methyl ester (EXAMPLE 43, 170 mg, 0.44 mmol) in methanol (5 mL) and the reaction stirred at rt for 24 h. The solvent was removed in vacuo and the residue partitioned between hydrochloric acid (1N, 30 mL) and ethyl acetate (3×3 mL). The combined organic fractions were dried (MgSO4) and concentrated in vacuo to give the title compound as a yellow solid. δH (DMSO): 2.71 (1H, dd), 2.91 (1H, dd), 3.56 (1H, d), 4.38–4.46 (1H, m), 4.77 (1H, s), 6.76 (1H, s), 7.11–7.16 (1H, m), 7.19–7.27 (4H, m), 7.45 (1H, s), 8.44–8.52 (2H, m); m/z (ES+)=374 [M+H]+.
