실험 절차

A mixture of tert-butyl N-[(3S)-1-[1-methyl-5-[6-(6-methylpyrazin-2-yl)pyrazolo[4,3-c]pyridin-1-yl]-2-oxo-3-pyridyl]-3-piperidyl]carbamate (0.2245 mmol; 116.0 mg) in TFA (1 mL) and dichloromethane (4 mL) was stirred at room temperature overnight. The mixture was concentrated and the residue was purified by reverse phase HPLC to afford 233 as an off-white solid (51.6 mg, 54%). 1H NMR (400 MHz, DMSO) δ 9.47-9.40 (s, 1H), 9.36-9.30 (s, 1H), 8.66-8.57 (s, 2H), 8.48-8.40 (s, 1H), 7.96-7.90 (d, J=2.5 Hz, 1H), 6.96-6.90 (d, J=2.5 Hz, 1H), 3.69-3.61 (d, J=6.6 Hz, 2H), 3.58-3.52 (s, 3H), 2.83-2.72 (t, J=9.7 Hz, 1H), 2.63-2.58 (s, 3H), 2.30-2.23 (m, 1H), 1.88-1.81 (d, J=9.0 Hz, 1H), 1.74-1.68 (d, J=13.3 Hz, 1H), 1.63-1.53 (d, J=12.8 Hz, 1H), 1.18-1.06 (m, 1H); MS (ESI) m/z: 417.2 [M+H]+
