Procedure

A mixture of tert-butyl N-[(3S)-1-[4-methyl-6-[6-(6-methylpyrazin-2-yl)pyrazolo[4,3-c]pyridin-1-yl]-3-oxo-pyrazin-2-yl]-3-piperidyl]carbamate (0.3505 mmol; 181.4 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 241 as an off-white solid (28.1 mg, 18%). 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: 418.2 [M+H]+
