Procedure
To a stifled solution of N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-6-(1-(4-(dimethylamino)butanoyl)-1,2,3,6-tetrahydropyridin-4-yl)-1-isopropyl-1H-pyrazolo[3,4-b]pyridine-4-carboxamide (1 equiv.) in EtOH, 10% Pd/C in catalytic amount was added and stirred it at room temperature under hydrogen pressure (bladder pressure) for 3-16 h hr. On completion of reaction, reaction mass was filtered through celite bed, then filtrate was concentrated under reduced pressure to give the desired product. LCMS: 536.40 (M+1)+; HPLC: 83.00% (@ 254 nm) (Rt:4.917); 1H NMR (DMSO-d6, 400 MHz) δ 11.54 (s, 1H), 8.75 (t, 1H), 8.27 (s, 1H), 7.52 (s, 1H), 5.89 (s, 1H), 5.20-5.17 (m, 1H), 4.57-4.54 (m, 1H), 4.36 (d, 2H, J=4.8 Hz), 4.01-3.98 (m, 1H), 3.32 (1H merged with DMSO peak), 3.19-305 (m, 2H), 2.72-2.67 (m, 2H), 2.40 (m, 2H), 2.40 (s, 6H) 2.20 (s, 3H), 2.12 (s, 3H), 2.04-1.91 (m, 2H), 1.79-1.63 (m, 4H), 1.48 (d, 6H, J=6.4 Hz).
