Procedure

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.) was suspended in DMF and N1,N1,N3-trimethylpropane-1,3-diamine (5 equiv.) was added to it. The reaction mixture was stirred at room temperature for overnight. On completion of reaction, solvent was removed under reduced pressure and residue was purified by prep. HPLC chromatography to provide the desired compound (30% yield). LCMS: 544.25 (M+1)+; HPLC: 99.96% (@ 254 nm) (Rt; 4.732); 1H NMR (DMSO-d6, 400 MHz) δ 11.55 (bs, 1H), 10.14-9.80 (m, 1H), 8.95 (bs, 1H), 8.40-8.35 (m, 3H), 8.22-8.19 (m, 1H), 7.75-7.69 (m, 2H), 5.91 (s, 1H), 5.35-5.32 (m, 1H), 4.42 (d, 2H, J=3.6 Hz), 3.08-2.98 (m, 6H), 2.80-2.62 (m, 8H), 2.23 (s, 3H), 2.13 (s, 3H), 2.07 (m, 2H). 1.55 (d, 6H, J=6.4 Hz).
