Versuchsvorschrift

To a stirred solution of tert-butyl 4-(4-(((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)carbamoyl)-1-isopropyl-1H-pyrazolo[3,4-b]pyridin-6-yl)-5,6-dihydropyridine-1(2H)-carboxylate (2.8 g, 5.4 mmol) in DCM (15 mL), TFA (13 mL) was added at 0° C. and stirred it at room temperature for 1 h. After completion of reaction, solvent was removed under reduced pressure and residue neutralized with saturated NaHCO3 solution Extraction was carried out using DCM; the combined organic layers were washed with water, brine and dried over anhydrous Na2SO4; filtered and concentrated under reduced pressure, finally the residue was washed with diethyl ether to provide the desired intermediate (1.5 g, 66.4%).
