Reaction Steps

To a solution of (racemic) N-(5-cyano-4-((2-methoxyethyl)amino)pyridin-2-yl)-7-(dimethoxymethyl)-6-(3-methyl-2-oxopyrrolidin-1-yl)-3,4-dihydro-1,8-naphthyridine-1(2H)-carboxamide (intermediate 330, 63 mg, 0.120 mmol) in THF (0.9 ml) and water (0.3 mL) was added 37% aqueous HCl (0.1 mL, 3.29 mmol) at room temperature and the reaction mixture was stirred for 4 h. The reaction mixture was quenched by the addition of saturated aqueous Na2CO3 and diluted with DCM. Phases were separated and the water phase was extracted with DCM. The combined organic layers were dried using Na2SO4, filtered and solvents were concentrated. The crude product was precipitated from DCM and EtOAc, filtered and dried to yield the title compound as a yellow solid.
