Reaction Steps

To a solution of tert-butyl 4-[6-[6-(2-fluoro-5-methyl-3-pyridyl)pyrazolo[4,3-c]pyridin-1-yl]pyrazin-2-yl]-1,4-diazepane-1-carboxylate (0.2113 mmol; 106.6 mg) in Methanol (5 mL) was added hydrochloric acid, 4.0 M in 1,4-Dioxane (5 mL). The resulting mixture was stirred at room temperature overnight. The mixture was concentrated and the residue was purified by reverse phase HPLC to afford 164 as a by-product (18.7 mg, 22%). 1H NMR (400 MHz, DMSO) δ 9.89-9.85 (s, 1H), 9.25-9.20 (s, 1H), 8.64-8.60 (s, 1H), 8.56-8.52 (d, J=2.6 Hz, 1H), 8.41-8.38 (s, 1H), 8.08-8.05 (s, 1H), 7.33-7.30 (s, 1H), 3.95-3.84 (m, 4H), 2.99-2.93 (m, 2H), 2.71-2.66 (m, 2H), 2.15-2.13 (s, 3H), 1.88-1.81 (m, 2H); MS (ESI) m/z: 403.2 [M+H]+
