Reaction Steps

Partially dissolved 1.37 g (8.00 mmol) 2-morpholin-4-ylmethyl-2-propenoic acid in 50 ml THF and chilled to 0° C. under N2. Added 1.06 ml (9.6 mmol) N-methylmorpholine and 833 μl (6.4 mmol) isobutyl chloroformate. Stirred at 0° C. for 1 hour and added a solution of 1.00 g (3.20 mmol) 6-amino-4-[(3-chloro-4-fluorophenyl)amino]-3-quinolinecarbonitrile in 5 ml pyridine. Stirred overnight at 25° C. Poured onto a mixture of ice and saturated sodium bicarbonate, extracted with ethyl acetate, dried organic layer with brine and sodium sulfate, and stripped solvent to a small volume. Loaded onto a column of silica gel, eluted with 1% methanol/ethyl acetate, stripped solvent from desired fractions and dried under vacuum, giving 139 mg of yellow-orange solid: mass spectrum (electrospray m/e): M+H=465.8, 468.0.
