실험 절차

To a 2 dram vial charged with 1.3 (0.0200 g, 0.0551 mmol), tetrakis(triphenylphosphine)palladium (0) (0.0127 g, 0.0110 mmol), cesium fluoride (0.0102 mL, 0.275 mmol), and 2-butoxy-5-methoxyphenylboronic acid 4.2 (0.0247 g, 0.110 mmol), was added DME (1 mL). The resulting mixture was then heated at 85° C. overnight. The reaction was allowed to cool and then filtered and concentrated. The crude was purified by combiflash (0 to 20% EtOAc/hexanes) yielding 4.3 (0.0241 g, 95% yield).
