Versuchsvorschrift

To a suspension of (8-((5-cyano-4-((2-methoxyethyl)amino)pyridin-2-yl)carbamoyl)-2-(dimethoxymethyl)-5,6,7,8-tetrahydro-1,8-naphthyridin-3-yl)methyl methanesulfonate (intermediate 170, 363 mg, 0.679 mmol) in THF (8 ml) was added methylamine 2 M in THF (5 ml, 10.00 mmol) at room temperature and the reaction mixture was stirred at room temperature for 18 h. The reaction mixture was diluted with saturated aqueous NaHCO3 and DCM. Phases were separated and the water phase was extracted with DCM (3×), organic phases were combined and dried using Na2SO4, filtered and concentrated. The crude product was purified using silica gel column chromatography eluting with a gradient of MeOH (including 3% NH3, 10-20%) in DCM. Fractions containing the product were combined and evaporated to yield the title compound as a colorless solid.
