Reaction Steps

To a stirred solution of 6-amino-4-[4-(benzyloxy)-3-chloroanilino]-7-ethoxy-3-quinolinecarbonitrile (0.89 g, 2.0 mmol) and diisopropylethylamine (0.47 ml, 2.7 mmol) in 16 ml of tetrahydrofuran at 0° C. was added a freshly-prepared solution of 6-chloro-2-hexenoyl chloride in 4 ml of tetrahydrofuran during 30 s. The mixture was then stirred at 25° C. for 2.5 h and partitioned between ethyl acetate and water. The organic layer was washed with water, dried and concentrated. The residue was chromatographed on silica gel with methylene chloride-ethyl acetate to give 0.83 g of amber solid; mass spectrum (electrospray, m/e) 574.8 (M+H)+.
