PROCEDURE
实验过程
According to the procedure described in Example 7(a), N-[2,2-dimethyl-1(S)-(pyridin-4-ylcarbamoyl)propyl]-3(R)-[3-[4-(pyridin-4-yl)phenyl]-1H-pyrrol-1-yl]succinamic acid benzyl ester (185 mg, 0.280 mmol) was hydrogenolyzed in EtOH (10 mL) and HOAc (1 mL) and fumished a solid that was triturated with EtOAc to give 60 mg (41%) of N-[2,2-dimethyl-1(S)-(pyridin-4-ylcarbamoyl)propyl]-3(R)-[3-[4-(pyridin-4-yl)phenyl]-1H-pyrrol-1-yl]succinamic acid as a yellow solid. 1H NMR (CD3OD): δ 8.54 (d, 2H, J=6.6 Hz), 8.33 (d, 2H, J=6.6 Hz), 7.73-7.68 (m, 4H), 7.64-7.59 (m, 4H), 7.32 (s, 1H), 6.91 (t, 1H J=2.4 Hz), 6.52 (dd, 1H, J=1.8, 2.9 Hz), 5.31 (t, 1H, J=7.5 Hz), 4.41 (s, 1H), 2.99 (dd, 1H, J=6.8, 16.7 Hz), 1.03 (s, 9H). Anal. Calculated for C30H31N5O4•0.6 H2O•0.2 EtOAc: C, 66.77; H, 6.15; N, 12.64. Found: C, 66.72; H, 5.99; N, 12.62.
