Reaction Steps

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, 0.2 mmol) was suspended in pyridine (1 mL) and acetyl chloride (0.016 g, 0.205 mmol) was added to it. The reaction mixture was stirred at room temperature for 5 h. On completion of reaction, water was added to it and extraction was carried out using 10% MeOH/DCM; the combined organic layers were washed with water, brine and dried over anhydrous Na2SO4; filtered and concentrated under reduced pressure. The residue was purified by prep HPLC to provide the desired compound (30% yield). LCMS: 560.00 (M+1)+; HPLC: 99.09% (@ 254 nm) (Rt; 4.685); 1H NMR (DMSO-d6, 400 MHz) δ 11.56 (s, 1H), 8.85 (t, 1H, J=5.2 Hz), 8.74 (s, 2H), 8.32 (s, 1H), 7.87 (s, 1H), 6.84 (s, 1H), 5.90 (s, 1H), 5.12-5.06 (m, 1H), 4.48 (d, 2H, J=12 Hz), 4.38 (d, 2H, J=5.2 Hz), 3.97 (m, 2H), 3.33-3.30 (m, 1H), 2.83 (s, 2H), 2.23 (s, 3H), 2.12 (s, 3H), 2.08 (s, 3H), 2.03-1.91 (m, 4H), 1.57 (s, 6H) 1.47 (s, 6H).
