실험 절차

N-[4-[[3-Chloro-4-(2-pyridylmethoxy)phenyl]amino]-3-cyano-7-ethoxy-6-quinolyl]-2-diethoxyphosphoryl-acetamide 1d (156 mg, 0.25 mmol) was dissolved in 3 mL of tetrahydrofuran in a dry ice bath, followed by dropwise addition of a solution of lithium bis(trimethylsilyl)amide (1 M) in toluene (375 μL, 0.38 mmol). After the reaction mixture was stirred for 45 minutes, a solution of tert-butyl (2S)-2-formylpyrrolidine-1-carboxylate 2c (100 mg, 0.50 mmol) in 2 mL of tetrahydrofuran was added. The reaction mixture was stirred for another 1 hour, then warmed up to room temperature and stirred for 12 hours. The reaction mixture was concentrated under reduced pressure and the resulting residue was purified by silica gel column chromatography with elution system A to obtain the title compound 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, yield 96.2%) as a light yellow solid.
