Reaction Steps
To a solution of 1,1-dimethylethyl (2-{4-[3-fluoro-6-(methyloxy)-1,5-naphthyridin-4-yl]-1-piperazinyl}ethyl)carbamate (725 mg, 1.79 mmol) in MeOH (9 mL) at 25° C. was added dropwise a 4M solution of HCl in dioxane (3.1 mL, 12.53 mmol). After 12 h, the solution was concentrated the residue neutralized using excess MP carbonate resin in DCM affording the free amine which was used without further purification: LCMS (ES) m/e 306 (M+H)+.
