실험 절차

To a suspension of (racemic) 1-(8-((5-cyano-4-((2-methoxyethyl)amino)pyridin-2-yl)carbamoyl)-2-(dimethoxymethyl)-5,6,7,8-tetrahydro-1,8-naphthyridin-3-yl)ethyl methanesulfonate (intermediate 182, 231 mg, 0.421 mmol) in DCM (8 ml) and DMF (0.5 ml) at 0° C. was added methylamine (2M in THF, 3 mL, 6.00 mmol). The reaction mixture was allowed to warm to room temperature and continued to stir over night. The reaction mixture was diluted with water and DCM, phases were separated and the water phase was extracted with DCM (3×), organic phases were combined, dried using Na2SO4, filtered and concentrated. The crude product was purified using silica gel column chromatography eluting with MeOH (including 3% NH3, 4-5%) in DCM to yield the title compound as a colorless solid.
