Versuchsvorschrift

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 MeOH (2 mL), methyl vinyl sulfone (0.063 g, 0.596 mmol) was added and stirred it at room temperature for 12 h. After completion of reaction, solvent was removed under reduced pressure and water was added to it. 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, finally the residue was washed with diethyl ether to provide the desired compound (41% yield). LCMS: 610.45 (M+1)+; HPLC: 97.26% (@ 254 nm) (Rt; 6.037); 1H NMR (DMSO-d6, 400 MHz) δ 11.54 (s, 1H), 8.82 (t, 1H), 8.27 (s, 1H), 7.80 (s, 1H), 6.88 (s, 1H), 5.89 (s, 1H), 5.21-5.17 (m, 1H), 4.37 (d, 2H, J=4.4 Hz), 3.32-3.25 (m, 4H), 3.02 (s, 3H), 2.95 (d, 2H, J=10.40 Hz), 2.73 (d, 2H, J=4 Hz), 2.67 (bs, 4H), 2.32 (m, 2H), 2.20 (s, 3H), 2.12 (s, 3H), 1.99-1.94 (m, 2H), 1.81-1.79 (m, 2H), 1.49 (d, 6H, J=6.4 Hz), 1.45 (m, 1H).
