実験手順

To a solution of compound 26d (100 mg, 0.273 mmol) and (R)—N-Boc-3-hydroxyproline in THF was added DIAD at 0° C. The resulting reaction mixture was stirred for 18 h. After dilution with water and extraction with EtOAc (3×), the combined organic extracts were dried over Na2SO4, filtered, and concentrated under reduced pressure. The resultant residue was purified by flash column chromatography on silica gel using 5% MeOH/CH2Cl2 to give compound 434 (95 mg). 1H NMR (CDCl3): δ 7.52 (d, J=8.6 Hz, 2H), 7.37-7.44 (m, 5H), 7.24-7.29 (m, 3H), 7.18-7.24 (m, 3H), 4.18-4.33 (m, 2H), 4.09-4.17 (m, 3H), 4.01-4.08 (m, 1H), 3.92 (br. S, 1H), 3.74 (br. s., 1H), 3.35-3.63 (m, 2H), 3.17-3.29 (m, 1H), 2.20-2.50 (m, 4H); MS m/z (M+H+) 506.0.
