A solution of 4-((8-((5-cyano-4-((2-methoxyethyl)amino)pyridin-2-yl)carbamoyl)-2-formyl-5,6,7,8-tetrahydro-1,8-naphthyridin-3-yl)methyl)-1-methyl-3-oxopiperazine 1-oxide (Example 222, 5 mg, 0.01 mmol) in DMSO (1 ml) was stirred at room temperature. After 30 h, the reaction mixture was concentrated and the residue purified by reverse phase chromatography: Atlantis C18 T3 column (3.5 um, 4.6×150 mm, 45° C.), eluting with 1:1 acetonitrile/water (containing 10 mM NH4OAc, 0.02% TFA). The product containing fraction was evaporated to give the title compound as a gray solid.
