Procedure
(R)-3-(7-Methyl-2-((2-(trimethylsilyl)ethoxy)methyl)-2H-indazol-5-yl)-1-oxo-1-(4-(piperidin-1-yl)piperidin-1-yl)propan-2-yl 4-(2-oxo-1,2-dihydroquinolin-3-yl)piperidine-1-carboxylate (102 mg, 0.14 mmol) was dissolved in trifluoroacetic acid (50% in dichloromethane, 6 mL), and stirred at room temperature for 2 h. The reaction was concentrated and purified by column chromatography (5:95:1 methanol/dichloromethane/triethylamine). The residue was dissolved in 10% methanol/dichloromethane and passed through a plug of basic alumina to give 56.4 mg (67%) as a white solid. 1H-NMR (CD3OD, 500 MHz) δ −0.50-0.01 (m, 0.7H), 0.50-0.85 (m, 0.8H), 1.00-2.05 (m, 16H), 2.05-2.55 (m, 7H), 2.55-3.00 (m, 4H), 3.00-3.15 (m, 2H), 3.70-4.50 (m, 4H), 5.41 (m, 0.3H), 5.48 (dd, J=9.5, 6.1, 0.6H), 7.01 (m, 1H), 7.11 (m, 1H), 7.21 (m, 1H), 7.36 (m, 2H), 7.44-7.65 (m, 2H), 7.90 (m, 1H). Mass spec.: 625.33 (MH)+.
