실험 절차

(4-Bromo-6-methoxy-quinolin-3-yl)-carbamic acid tert-butyl ester (22.7 g, 0.0643 mole) was dissolved in CH2Cl2 (200 mL) and treated with trifluoroacetic acid (100 mL). After 3.5 hr at RT, the mixture was concentrated and the residue was dissolved in water. The solution was made basic with aqueous sodium carbonate. The precipitate was filtered off, washed with water, and dried at 40° C. in vacuo overnight, to give the title compound (16.46 g, 101%) as a white solid: MS (ES) m/e 254/256 (M+H)+.
