Procedure
Isobutyl chloroformate (0.161 g, 1.18 mmol) was dropwise added into an ice cold solution of 4-morpholino-2-butynoic acid (0.25 g, 1.48 mmol) and N-methylmorpholine (0.15 g, 1.48 mmol) in 8 mL of tetrahydrofuan under N2. After stirring for 30 min, a solution of 025 g (0.74 mmol) of 6-amino-4-[(3-bromophenyl)amino]-3-quinolinecarbonitrile in 6 mL of pyridine was added dropwise and the mixture was stirred at 0° C. for 2 hr. The reaction was quenched with ice water, poured into saturated sodium bicarbonate and brine, and extracted with ethyl acetate. The ethyl acetate layer was concentrated and purified by thin-layer chromatography eluted with 15% methanol in ethyl acetate. The product was collected, and dried in vacuo to give 0.096 g (27%) of yellow solid; :mass spectrum (electrospray, m/e,) 490.1, 492.1 (M+H+); mp 145-148° C.
