A solution of tert-butyl N-[(3S)-1-[3-methoxy-6-[6-(6-methylpyrazin-2-yl)pyrazolo[4,3-c]pyridin-1-yl]pyrazin-2-yl]-3-piperidyl]carbamate (30 mg, 0.058 mmol) in hydrogen chloride (4 mol/l) in 1,4-dioxane (1.0 ml, 4.0 mmol) and 1,4-dioxane 1.0 mL was stirred at RT 2d. The reaction was concentrated and submitted for reverse phase HPLC to give 223 (7 mg, 27% yield.
