Versuchsvorschrift

tert-Butyl (2S)-2-[(E)-3-[[4-[[3-chloro-4-(2-pyridylmethoxy)phenyl]amino]-3-cyano-7-ethoxy-6-quinolyl]amino]-3-oxo-prop-1-enyl]pyrrolidine-1-carboxylate 2d (161 mg, 0.24 mmol) was dissolved in a solution of hydrogen chloride (2M) in 25 mL of 1,4-dioxane. After stirring for 12 hours, the reaction mixture was concentrated under reduced pressure and extracted with dichloromethane (50 mL×3). The combined organic extracts were washed with saturated brine (30 mL×2), dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure and the resulting residue was purified by silica gel column chromatography with elution system A to obtain the title compound (E)-N-[4-[[3-chloro-4-(2-pyridylmethoxy)phenyl]amino]-3-cyano-7-ethoxy-6-quinolyl]-3-[(2S)-pyrrolidin-2-yl]prop-2-enamide 2 (20 mg, yield 14.6%) as a yellow solid.
