Procedure

Tert-butyl 4-{2-carbamoyl-5-(3-isopropyl-4-(quinolin-3-yl)-1H-pyrazolo[3,4-b]pyridin-1-yl)phenylamino}piperidine-1-carboxylate (0.704 g) was dissolved in trifluoroacetic acid, followed by stirring at room temperature for 1 hr. The reaction solution was distributed between chloroform and saturated sodium bicarbonate water. The organic layer was washed with saturated saline and then dried over anhydrous sodium sulfate. After distillation of the solvent, the residue was purified by neutral silica gel column chromatography (chloroform/methanol) to obtain (76) (0.600 g, 99%) as a white solid.
