실험 절차

To a solution of 0.56 g (3.54 mmol) of 4-(2-methoxy-ethoxy)-but-2-ynoic acid and 0.46 g (3.4 mmol) of isobutyl chloroformate in 12 ml of tetrahydrofuran was added at 0° C. with stirring 0.36 g (3.54 mmol) of N-methylmorpholine. After 15 min, 1.0 g (2.95 mmol) of 6-amino-4-[(3-bromophenyl)amino]-quinoline-3-carbonitrile was added. After stirring 3 hr at 0° C. and 17 hr at room temperature, the mixture was poured into a saturated solution of sodium bicarbonate. The mixture was extracted with ethyl acetate and the organic layer was dries over magnesium sulfate. The solvent was remove and the residue was purified by chromatography on silica gel eluting with chloroform-ethyl acetate mixtures to give 0.53 g of 4-(2-Methoxy-ethoxy)-but-2-ynoic acid[4-(3-bromo-phenylamino)-3-cyano-quinolin-6-yl]-amide as a yellow powder: mass spectrum (electrospray, m/e,): M+H 480.9.
