A 4N solution of HCl in EtOAc (10 mL, 40 mmol) was added to stirred solution of tert-butyl{1-[4-(2-phenyl-9-pyrazin-2-yl[1,2,4]triazolo[4′,3′:1,6]pyrido[2,3-b]pyrazin-3-yl)phenyl]cyclobutyl}carbamate (8-7, 0.110 g, 0.193 mmol) in MeOH (2 mL) and DCM (2 mL). After 4 hours the reaction mixture was concentrated in vacuo to give 1-[4-(2-phenyl-9-pyrazin-2-yl[1,2,4]triazolo[4′,3′:1,6]pyrido[2,3-b]pyrazin-3-yl)phenyl]cyclobutanamine hydrochloride (8-8) as an orange/tan solid. HRMS (M+H)+: observed=471.2076, calculated=471.2040.
