실험 절차

The starting material 5-bromo-1-(4-methoxybenzyl)-3-methyl-1H-pyrazolo[3,4-b]pyridine (7) (134 mg, 0.402 mmol, 1 eq) and (3-acrylamidophenyl)boronic acid (153) (100 mg, 0.366 mmol, 1 eq) in DME (10 mL) was degassed and purged under argon atmosphere for 10 min. To this reaction mixture was charged Cs2CO3 (233 mg, 0.732 mmol, 2 eq) followed by addition of Pd(PPh3)4 (0.016 mg, 0.03 mmol) and degassing and purging under argon for additional 10 min. The reaction mixture was heated at 100° C. for 16 h in a sealed tube. After completion of the reaction, the solvents were removed and reaction mixtures were extracted into EtOAc, dried over Na2SO4 and the solvents distilled off. The crude material was submitted for flash column purification using 40% EtOAc in hexane to obtain off-white solid compound N-(3-(1-(4-methoxybenzyl)-3-methyl-1H-pyrazolo[3,4-b]pyridin-5-yl)phenyl)acrylamide 154. MS m/z 397.2 (M+H)+.
