Procedure

To a stirred solution of N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-1-(piperidin-4-yl)-6-(2,2,6,6-tetramethyl-1,2,3,6-tetrahydropyridin-4-yl)-1H-pyrazolo[3,4-b]pyridine-4-carboxamide (0.1 g, 0.193 mmol) in DMF (1 mL), K2CO3 (0.032 g, 0.232 mmol) and benzyl bromide (0.04 g, 0.232 mmol) were added. Resulting reaction mixture was stirred at 80° C. for 12 h. On completion of reaction, water was added to it and extraction was carried out using DCM; the combined organic layers were washed with water, brine and dried over anhydrous Na2SO4. Solvent was removed under reduced pressure and residue was purified by prep HPLC to provide the desired compound (21.3% yield). LCMS: 608.45 (M+1)+; HPLC: 94.92% (@ 254 nm) (Rt;4.640); 1H NMR (DMSO-d6, 400 MHz) δ 11.54 (s, 1H), 9.70 (bs, 1H), 8.86 (s, 1H), 8.37 (s, 1H), 7.90 (s, 1H), 7.54-7.52 (m, 5H), 6.85 (s, 1H), 5.90 (s, 1H), 5.17 (m, 1H), 4.40 (m, 4H), 3.55 (d, 2H, J=12 Hz), 3.41-3.35 (m, 2H), 2.83 (m, 2H), 2.32-2.41 (m, 2H), 2.23 (s, 3H), 2.22-2.13 (m, 2H), 2.12 (s, 3H), 1.57 (s, 6H), 1.47 (s, 6H).
