실험 절차

Tert-butyl 4-{3-[(3R)-3-{[(1S)-1-(3-{2-[2-(2-fluoroethoxy)ethoxy]ethoxy}phenyl)-3-methoxy-3-oxopropyl]carbamoyl}piperidin-1-yl]-3-oxopropyl}piperidine-1-carboxylate (20.3 mg, 27 μmol) was solved in tert.-butanol (0.77 mL) and methanol (0.76 mL) and barium hydroxide octahydrate (42 mg, 0.13 mmol) was added. After stirring for 60 minutes room temperature the solvent was distilled off at 0° C. by high vacuum. The residue was solved in water (1 mL) and acidified by formic acid (2 mL). After 18 hours at 5° C. additional formic acid (2 mL) was added. 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 8.4 mg of (3S)-3-(3-{2-[2-(2-fluoroethoxy)ethoxy]ethoxy}phenyl)-3-[({(3R)-1-[3-(piperidin-4-yl)propanoyl]piperidin-3-yl}carbonyl)amino]propanoic acid.
