実験手順
As described in Example 1(a), N-[2,2-dimethyl-1(S)-(methylcarbamoyl)propyl]-3(S)-[1-(4-fluorophenyl)-1H-pyrrol-3-yl]succinamic acid benzyl ester was hydrogenolyzed in EtOH after 1.5 hours. Trituration with MTBE/hex gave in quantitative yield N-[2,2-dimethyl-1(S)-(methylcarbamoyl)propyl]-3 (S)-[1-(4-fluorophenyl)-1H-pyrrol-3-yl]succinamic acid as a colorless amorphous solid. 1H NMR: δ 7.27-7.23 (m, 2H), 7.07 (t, 2H, J=8.6 Hz), 6.90-6.89 (m, 2H), 6.21 (t, 1H, J=2.2 Hz), 6.13-6.10 (m, 1H), 4.24 (d, 1H, J =9.6 Hz), 4.03 (dd, 1H, J=5.2, 8.5 Hz), 3.14 (dd, 1H, J=8.5, 16.6 Hz), 2.80 (dd, 1H, J=5.7, 16.7 Hz), 2.72 (d, 3H, J=4.8 Hz), 0.94 (s, 9H). Anal. Calculated for C21H26N3O4F: C, 63.17; H, 6.80; N, 10.09. Found: C, 62.89; H, 6.93; N, 9.81.
