Versuchsvorschrift

A solution of 3-bromo-1-isopropyl-6-(4-(morpholinomethyl)phenyl)-1H-pyrazolo[3,4-b]pyridine-4-carboxylic acid (0.8 g, 1.74 mmol) and 3-(aminomethyl)-4,6-dimethylpyridin-2(1H)-one (0.531 g, 3.49 mmol) in DMSO (8 mL) and was stirred at room temperature for 15 min. Then PYBOP (1.36 g, 2.62 mmol) was added to it and stirring was continued for 12 hr. After completion of the reaction, reaction mass was poured into ice to obtain solid, which was filtered and solid was purified by silica gel column chromatography to obtain the desired compound (39% yield). LCMS: 593.20 (M+1)+; HPLC: 97.49% (@ 254 nm) (Rt; 5.338); 1H NMR (DMSO-d6, 400 MHz) δ 11.48 (bs, 1H), 8.67 (t, 1H, J=4.8 Hz), 8.18 (d, 2H, J=8.4 Hz), 7.73 (s, 1H), 7.47 (d, 2H, J=8.4 Hz), 5.87 (s, 1H), 5.33-5.30 (m, 1H), 4.40 (d, 2H, J=4.4 Hz), 3.58 (bs, 4H), 3.53 (s, 2H), 2.38 (bs, 4H), 2.26 (s, 3H), 2.11 (s, 3H), 1.52 (d, 6H, J=6.4 Hz).
