Procedure

To a stirred solution of N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-1-isopropyl-6-(1-(piperidin-4-yl)-1,2,3,6-tetrahydropyridin-4-yl)-1H-pyrazolo[3,4-b]pyridine-4-carboxamide (0.2 g, 0.397 mmol) in DCM (5 mL), Et3N (0.06 g, 0.596 mmol) and mesyl chloride (0.046 g, 0.403 mmol) were added at 0° C. and stirred it at room temperature for 2 h. After completion, reaction was quenched with ice-water. Extraction was carried out using DCM; the combined organic layers were washed with water, brine and dried over anhydrous Na2SO4; filtered and concentrated under reduced pressure to afford crude material which was purified by prep. HPLC to give the desired compound. LCMS: 582.30 (M+1)+; HPLC: 92.74% (@ 254 nm) (Rt; 5.006); 1H NMR (DMSO-d6, 400 MHz) δ 11.55 (s, 1H), 9.86 (bs, 1H), 8.87 (t, 1H, J=4.8 Hz), 8.34 (s, 1H), 7.90 (s, 1H), 6.93 (s, 1H), 5.90 (s, 1H), 5.23-5.20 (m, 1H), 4.39 (d, 2H, J=4.4 Hz), 4.08 (bs, 2H), 3.80 (bs, 2H), 3.72 (d, 2H, J=11.60 Hz), 3.30 (bs, 2H), 3.15 (d, 2H, J=15.60 Hz), 2.93 (s, 3H), 2.84-2.76 (m, 2H), 2.27 (m, 1H), 2.21 (s, 3H), 2.12 (s, 3H), 1.81-1.73 (m, 2H), 1.51 (d, 6H, J=6.8 Hz).
