To a solution of tert-butyl (1-{4-[3-(1-methyl-1H-imidazol-4-yl)-9-phenyl[1,2,4]triazolo[3,4-f]-1,6-naphthyridin-8-yl]phenyl}cyclobutyl)carbamate (1-8) (2.52 g, 4.41 mmol) in MeOH (5 mL) and DCM (15 mL) was added a 4N solution of HCl in EtOAc (22 mL, 88 mmol). The sealed reaction mixture was permitted to stir at room temperature. After 4 hours the reaction mixture was concentrated in vacuo to give 1-{4-[3-(1-methyl-1H-imidazol-4-yl)-9-phenyl[1,2,4]triazolo[3,4-f]-1,6-naphthyridin-8-yl]phenyl}cyclobutanamine dihydrochloride (1-9) as a yellow solid. HRMS (M+H)+: observed=472.2249, calculated=472.2244.
