실험 절차

To a stirred solution of N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-1-isopropyl-6-(1-(piperidin-4-yl)-1,2,3,6-tetrahydropyridin-4-yl)-1H-pyrazolo[3,4-b]pyridine-4-carboxamide (0.08 g, 0.159 mmol) in EtOH (2 mL), 10% Pd/C in catalytic amount was added and stirred it at room temperature under hydrogen pressure (balloon pressure) for 3-4 hr. On completion of reaction, reaction mass was filtered through celite bed, then filtrate was concentrated under reduce pressure, finally the residue was washed with diethyl ether to provide the desired compound (62% yield). LCMS: 506.40 (M+1)+; HPLC: 90.48% (@ 254 nm) (Rt; 4.196); 1H NMR (DMSO-d6, 400 MHz) δ 11.55 (bs, 1H), 9.79 (bs, 1H), 8.76 (t, 1H), 8.58 (bs, 1H), 8.27 (s, 1H), 7.47 (s, 1H), 5.90 (s, 1H), 5.17 (m, 1H), 4.37 (d, 2H, J=4.4 Hz), 3.60 (bs, 2H), 3.45 (bs, 2H), 3.16 (m, 4H), 2.95 (m, 4H), 2.21 (s, 3H), 2.12 (s, 3H), 2.25-2.05 (m, 4H), 1.85 (m, 2H), 1.50 (d, 6H, J=6.4 Hz).
