실험 절차

To a solution of 3-[3-(2-methoxy-phenyl)-1H-pyrazolo[3,4-b]pyridin-5-yl]-benzoic acid (18 mg, 0.05 mmol) in DMF (1 mL) was added HATU (20 mg, 0.05 mmol) and 1-(2-pyrimidyl)piperazine (11 uL, 0.08 mmol). The reaction solution was stirred for 16 hours at ambient temperature. The crude product was extracted into ethyl acetate and washed with H2O. The organic layer was dried over Na2SO4, filtered, and adsorbed onto silica gel. Purification by flash chromatography with a gradient of ethyl acetate (containing 10% MeOH) and hexanes afforded the title compound as a white powder (7.2 mg, 28% yield). 1H NMR (500 MHz, CD3OD) δ 8.85 (d, J=2 Hz, 1H), 8.42 (d, J=2 Hz, 1H), 8.35 (d, J=4.5 Hz, 2H), 7.83 (d, J=8 Hz, 1H), 7.79 (s, 1H), 7.64 (m, 2H), 7.50 (m, 2H), 7.20 (d, J=8.5 Hz, 1H), 7.11 (t, J=8 Hz, 1H), 6.64 (t, J=4.5 Hz, 1H), 3.96 (br s, 2H), 3.89 (s, 3H), 3.86 (br s, 4H), 3.60 (br s, 2H).
