実験手順

Tert-butyl 4-(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-dihydropyridin-1(2H)-yl)piperidine-1-carboxylate (0.5 g, 0.829 mmol) was taken in DCM (6 mL), TFA (2 mL) was added and stirred at room temperature for 1 h. After completion of reaction, solvent was removed under reduced pressure, 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 acetonitrile followed by diethyl ether to provide the desired compound. LCMS: 504.35 (M+1)+; HPLC: 99.26% (@ 254 nm) (Rt;4.223); 1H NMR (DMSO-d6, 400 MHz) δ 11.56 (bs, 1H), 10.25 (bs, 1H), 8.87 (t, 1H, J=4.8 Hz), 8.80 (bs, 1H), 8.55 (bs, 1H), 8.34 (s, 1H), 7.89 (s, 1H), 6.93 (bs, 1H), 5.90 (s, 1H), 5.21 (m, 1H), 4.39 (d, 2H, J=4.8 Hz), 4.08 (bs, 2H), 3.75 (bs, 2H), 3.30 (m, 3H), 3.16-3.12 (m, 1H), 2.96 (m, 3H), 2.32 (m, 2H), 2.21 (s, 3H), 2.12 (s, 3H), 1.86 (m, 2H), 1.52 (d, 6H, J=6.8 Hz).
