Procedure

To a stirred solution of 6-(3-(bromomethyl)phenyl)-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-1-isopropyl-1H-pyrazolo[3,4-b]pyridine-4-carboxamide (1 equiv.) in a DMF, dimethylamine (5 equiv.) was added at 0° C. & resulting reaction mixture stirred for overnight. After completion of reaction, water was added to it and extraction was carried out using EtOAc. The combined organic layers were washed with water, dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure to obtain the crude material which was purified by column chromatography to give pure final compounds (40% yield). LCMS: 473.20 (M+1)+; HPLC: 99.89% (@ 254 nm) (Rt; 5.325); 1H NMR (DMSO-d6, 400 MHz) δ 11.52 (s, 1H), 8.96 (bs, 1H), 8.35 (s, 1H), 8.13-8.10 (m, 3H), 7.50 (t, J=8.4 Hz, 1H), 7.43-7.41 (m, 1H), 5.89 (s, 1H), 5.34-5.31 (m, 1H), 4.41 (d, J=4 Hz, 2H), 3.50 (s, 2H), 2.23 (s, 3H), 2.19 (s, 6H), 2.12 (s, 3H), 1.54 (d, J=6.8 Hz, 6H).
