実験手順

Isobutyl chloroformate (0.785 g, 5.75 mmol) was dropwise added into an ice cold solution of 4-(N-ethylpiperazino)-2-butynoic acid (1.75 g, 8.85 mmol) and N-methylmorpholine (1.3453 g, 13.3 mmol) in 50 mL of tetrahydrofuan under N2. After stirring for 30 min, a solution of 1.5 g (4.42 mmol) of 6-amino-4-[(3-bromophenyl)amino]-3-quinolinecarbonitrile in 10 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 flash column chromatography. The product fractions were collected, and dried in vacuo to give 1.07 g (46%) of light brown solid; ESMS m/z 517.1, 519.1 (M+H+); mp 161° C. (dec).
