実験手順

Route A: To a solution of 2-(S)-[(5-chloro-1H-pyrrolo[2,3-c]pyridine-2-carbonyl)amino]-3-(4-fluorophenyl)propionic acid (EXAMPLE 228, 1.4 g, 3.87 mmol) in DMF (35 mL) was added HATU (1.77 g, 4.64 mmol) and the reaction stirred for 10 min. 4-Hydroxypiperidine (0.43 g, 4.26 mmol) was added, followed by DIPEA (0.8 mL, 4.64 mmol,) and the reaction stirred at rt for 16 h. Solvent was removed in vacuo and the crude material partitioned between ethyl acetate (50 mL) and water (50 mL). The organics were washed with sodium bicarbonate (2×30 mL) and brine (2×30 mL), dried (MgSO4) and the solvent removed in vacuo. Purification by column chromatography (SiO2, 96:4 dichloromethane/methanol) gave the title compound. m/z (ES+)=445.15 [M+H]+; RT=3.24 min.
