Procedure

To a solution of (R)-3-(7-methyl-1H-indazol-5-yl)-2-(4-(2-oxo-1,2-dihydroquinolin-3-yl)piperidine-1-carbonyloxy)propanoic acid (50 mg, 0.11 mmol), diisopropylethylamine (37 μL, 0.21 mmol), and piperidine (21 μL, 2.0 equiv) in dimethylformamide (0.5 mL) and dichloromethane (0.5 mL) at 0° C. was added PyBOP® (57.6 mg, 0.11 mmol). The reaction was stirred at 0° C. for 4 h. The reaction was concentrated and purified by column chromatography (95:5:1 to 90:10:1 dichloromethane/methanol/triethylamine). The resulting residue was dissolved in 5% methanol/dichloromethane and passed through a basic alumina column to give 55 mg (93%) as a white powder. 1H-NMR (CD3OD, 500 MHz) δ 0.75-1.70 (m, 9H), 1.70-1.95 (m, 4H), 2.51 (s, 3H), 2.72-3.04 (m, 3H), 3.11 (m, 4H), 3.19-3.58 (m, 4H), 3.98-4.49 (m, 2H), 5.47 (dd, J=7.3, 7.3, 1H), 7.07 (s, 1H), 7.17 (m, 1H), 7.27 (m, 1H), 7.43 (m, 2.5H), 7.58 (d, J=7.3, 1H), 7.65 (bs, 0.5H), 7.96 (s, 1H). Mass spec.: 542.29 (MH)+.
