실험 절차

840 mg of tert-butyl [3-({4-carbamoyl-5-[(2-fluoro-4-iodophenyl)amino]pyridin-3-yl}oxy)phenyl]carbamate (1.488 mmol, 1 eq.) were dissolved in 8 mL dichloromethane under a nitrogen atmosphere. Then 1.6 ml of TFA were added and the brownish solution was stirred at room temperature for 18 hours. Then 4 ml of saturated aqueouse NaHCO3 solution was added and the mixture was stirred for 4 hours while a suspension was forming, that was filtered off. Drying of the precipitate in vacuo yielded 615 mg of the analytically pure target compound (1.488 mmol, 87% yield) as a yellowish solid.
