実験手順
Analogous to the procedure described for Example 1A, Step F, 4-{2-[2-(3-hydroxy-4-phenyl-butyl)-5-oxo-pyrrolidin-1-yl]-ethoxy}-benzoic acid ethyl ester (52 mg, 0.122 mmol) was hydrolyzed with 6N NaOH (1 mL) to yield the title compound (41.5 mg). 1H NMR (CDCl3) δ7.98 (d, 2H), 7.32-7.16 (m, 5H), 6.85 (m, 2H), 4.13 (m, 2H), 3.92 (m, 1H), 3.81 (m, 1H), 3.75 (m, 1H), 3.40 (m, 1H), 2.82 (m,1H), 2.66 (m, 1H), 2.36 (m, 2H), 2.10 (m, 2H), 1.70-1.34 (m, 5H); MS 398.4 (M+1), 396.3 (M−1).
