실험 절차

1.70 g (4.08 mmol) of N-{4-[(3-bromo-1H-pyrrolo[2,3-b]pyridin-4-yl)methyl]-3-fluorophenyl}-2,2,2-trifluoroacetamide are dissolved in 50 ml of THF and cooled to −78° C. A solution of n-butyllithium (2.81 ml, 1.6M in hexane, 4.49 mmol) is added dropwise. After 15 min, a solution of 860 mg (4.49 mmol) of p-toluenesulfonyl chloride in 5 ml of THF is added dropwise. The mixture is allowed to warm to RT and stirred for 1 h. Water and saturated sodium bicarbonate solution are then added, and the mixture is extracted with ethyl acetate. The organic phase is dried over sodium sulfate. The solvent is removed under reduced pressure and the residue is purified by column chromatography on silica gel (mobile phase dichloromethane:ethanol=50:1).
