Versuchsvorschrift

Tert-butyl 4-{3-[(3R)-3-{[(1S)-1-{5-[(3-cyano-4-fluorobenzyl)oxy]pyridin-3-yl}-3-methoxy-3-oxopropyl]carbamoyl}piperidin-1-yl]-3-oxopropyl}piperidine-1-carboxylate (3.2 mg, 10 μmol) as solved in tert.-butanol (0.15 mL) and methanol (0.13 mL) and barium hydroxide octahydrate (7.4 mg, 20 μmol) was added. After stirring for 45 minutes at room temperature the solvent was distilled off at 0° C. by high vacuum. The residue was solved in water (0.3 mL) and acidified by formic acid (0.9 mL). After 3 hours at room temperature the solvent was distilled off at 0° C. by high vacuum and the residue was purified by preparative HPLC to yield 0.8 mg of (3R)-3-{5-[(3-cyano-4-fluorobenzyl)oxy]pyridin-3-yl}-3-[({(3S)-1-[3-(piperidin-4-yl)propanoyl]piperidin-3-yl}carbonyl)amino]propanoic acid.
