反応手順
A sealed tube was charged with 7-methoxy-N-((6-(3,4,5-trifluorophenyl)-[1,2,4]triazolo[4,3-b]pyridazin-3-yl)methyl)-1,5-naphthyridin-4-amine hydrochloride (238 mg, 502 μmol) and HBr (5966 μl, 52740 μmol), sealed, then placed in a 120° C. oil bath for 48 h. Cooled to room temperature and brought to pH˜14 with NaOH (6N). Isolated solid by filtration which was purified by RPHPLC to afford 8-((6-(3,4,5-trifluorophenyl)-[1,2,4]triazolo[4,3-b]pyridazin-3-yl)methylamino)-1,5-naphthyridin-3-ol as its formate salt. MS (ESI pos. ion) m/z: 424 (MH+). Calc'd exact mass for C20H12F3N2O: 423.
