実験手順

A solution of 1-isopropyl-6-(4-methylpiperazin-1-yl)-1H-pyrazolo[3,4-b]pyridine-4-carboxylic acid (0.2 g, 0.600 mmol) and 3-(aminomethyl)-4,6-dimethylpyridin-2(1H)-one (0.182 g, 1.197 mmol) in DMSO (2 mL) and was stirred at room temperature for 15 min. Then PyBOP (0.468 g, 0.900 mmol) was added to it and stirring was continued for 12 hr. After completion of the reaction, saturated NaHCO3 solution was added to it and extraction was carried out using DCM. The combined organic layers were washed with water, 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 (53% yield). LCMS: 438.15 (M+1)+; HPLC: 96.67% (@ 254 nm), (Rt; 4.516); 1H NMR (DMSO-d6, 400 MHz) δ 11.54 (s, 1H), 9.75 (s, 1H), 8.62 (s, 1H), 8.06 (s, 1H), 7.20 (s, 1H), 5.89 (s, 1H), 5.04-4.99 (m, 1H), 4.58 (d, 2H, J=14 Hz), 4.36 (d, 2H, J=4.4 Hz), 3.55 (d, 2H, J=11.20 Hz), 3.24 (t, 2H, J=12.40 Hz), 3.12 (m, 2H), 2.84 (s, 3H), 2.20 (s, 3H), 2.12 (s, 3H), 1.45 (d, 6H, J=6.8 Hz).
