To a solution of tert-butyl{1-[4-(3-hydroxy-9-phenyl[1,2,4]triazolo[3,4-f]-1,6-naphthyridin-8-yl)phenyl]cyclobutyl}carbamate (1-6a) (1.14 g, 2.25 mmol) in MeOH (5 mL) and DCM (15 mL) was added a 4N solution of HCl in EtOAc (22 mL, 88 mmol) at room temperature. After 4 hours the reaction mixture was concentrated in vacuo to give 8-[4-(1-aminocyclobutyl)phenyl]-9-phenyl[1,2,4]triazolo[3,4-f]-1,6-naphthyridin-3-ol hydrochloride (1-16) as a yellow solid. HRMS (M+H)+: observed=408.1803, calculated=408.1819.
