Reaction Steps

To a stirred mixture of 3-(2-fluoro-5-methoxyphenyl)-5-(1-methyl-1H-pyrazol-4-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridine (37.0 mg, 0.09 mmol) in methanol (5.0 mL) was added 6 M HCl in water (0.66 mL). The reaction mixture was stirred at 60° C. for 3 days. Volatile solvent was evaporated in vacuo, and the crude was diluted into ethyl acetate (˜30 mL). The organic layer was washed with saturated aqueous sodium bicarbonate solution, water and brine, dried over Na2SO4, filtered, and concentrated under reduced pressure. Trituration from ether-heptanes afforded 172 as a solid (15.3 mg, 52.1%). 1H NMR (400 MHz, DMSO) δ 13.88 (s, 1H), 9.06 (s, 1H), 8.25 (s, 1H), 7.97 (s, 1H), 7.88 (s, 1H), 7.36 (t, J=9.6 Hz, 1H), 7.31 (dd, J=5.7, 3.2 Hz, 1H), 7.09 (s, 1H), 3.88 (s, 3H), 3.83 (s, 3H). LC/MS: m/z 324.0 [M+1]
