Hydrochloric Acid → 5-(1-(6-(1,4-diazepan-1-yl)pyridin-2-yl)-1H-pyrazolo[4,3-c]pyridin-6-yl)-3-methylpyrazin-2-amine

Participants

Reaction Steps

To a solution of tert-butyl 4-[6-[6-(5-amino-6-methyl-pyrazin-2-yl)pyrazolo[4,3-c]pyridin-1-yl]-2-pyridyl]-1,4-diazepane-1-carboxylate (0.2293 mmol; 115 mg) in Methanol (10 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 208 as an off-white solid (4.0 mg, 4.3%). MS (ESI) m/z: 402.1 [M+H]+
