Reaction Steps

To a stirred solution of 6-(4-(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 dry DMF, 1-methylpiperazine (5 equiv.) was added at 0° C. and reaction mixture was 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. The residue was purified by column chromatography/preparative HPLC to give the desired compound (5% yield). LCMS: 528.25 (M+1)+; HPLC: 98.21% (@ 254 nm) (Rt; 4.802); 1H NMR (DMSO-d6, 400 MHz) δ 11.55 (s, 1H), 8.94 (bs, 1H), 8.36 (s, 1H), 8.19 (d, J=8.4 Hz, 2H), 8.13 (s, 1H), 7.46 (d, J=7.6 Hz, 2H), 5.89 (s, 1H), 5.33-5.30 (m, 1H), 4.41 (d, J=4 Hz, 2H), 3.52 (s, 3H), 2.30-2.45 (m, 7H), 2.21 (s, 3H), 2.15 (s, 3H), 2.12 (s, 3H), 1.54 (d, J=6.8 Hz, 6H).
