Versuchsvorschrift

3-Chloro-5-methyl-2H-isoquinolin-1-one (50 mg, 0.26 mmol), 2-(4-methylpiperazin-1-yl)pyrimidine-5-boronic acid pinacol ester (118 mg, 0.39 mmol), K2CO3 (73 mg, 0.52 mmol) and Pd(dppf)Cl2 (10 mg, 0.013 mmol) in DME/EtOH/H2O 4:0.5:1 (2.75 mL) were added to a microwave vial and the reaction mixture purged with N2 for 10 min. The reaction mixture was irradiated using a microwave reactor (300 W, 100° C., 60 min). The reaction mixture was filtered through celite and concentrated in vacuo. The crude material was purified by silica gel column chromatography, eluting with CH2Cl2 and increasing the polarity to 50% MeOH/CH2Cl2. The crude material was trituared with MeOH and washed with isohexane to afford 5-methyl-3-[2-(4-methyl-piperazin-1-yl)-pyrimidin-5-yl]-2H-isoquinolin-1-one as an off-white solid (28 mg, 32%).
