실험 절차

Trifluoroacetic acid (1.5 ml, 19.47 mmol) was added dropwise to an ice-cooled solution of 1,1-dimethylethyl (2R)-2-[({4-[(phenylmethyl)oxy]-3-[(3-pyridinylamino)carbonyl]phenyl}oxy)methyl]-1-pyrrolidinecarboxylate (may be prepared as described in Description 73; 500 mg, 0.99 mmol) in dichloromethane (15 ml). After stirring at 25° C. for 2 h, the pH of the solution was adjusted to 7-8 by adding aqueous NaHCO3 solution. The mixture was extracted with dichloromethane. The dichloromethane layer was washed with brine, dried over Na2SO4, and concentrated to obtain a crude product. Half of the crude product was purified by pre-HPLC (Gilson GX-281, waters X-Bridge 5 μm, 100*19 mm; A: 0.04% NH3.H2O/water, B: CH3CN; 0-7 min, 35%-50%; 7-14 min, 95%; RT=6.5 min) to yield the title compound as a light yellow solid. 70 mg.
