실험 절차

To a solution of [(3-bromo-4-fluorophenyl)methyl]methylamine (0.52 g, 2.39 mmol) in p-dioxane/H2O (15/5 mL) was added {3-[(4-{[(1,1-dimethylethyl)oxy]carbonyl}-1-piperazinyl)methyl]phenyl}boronic acid (1.15 g, 3.60 mmol), Pd(PPh3)4 (139 mg, 0.12 mmol), and K2CO3 (1.33 g, 9.6 mmol). The mixture was heated with a microwave at 150° C. for 15 min. The organic layer was separated, concentrated. The residue was redissolved in EtOAc (˜70 mL), which was washed with H2O (20 mL), brine (20 mL), dried over Na2SO4, filtered, concentrated and purified by CombiFlash chromatograph to afford the title compound 0.65 g (66%). LC-MS m/z 414 (M+H)+.
