Next, 2M Na2CO3 (38 μL), ethanol (42 μL), and water (56 μL) were added. The solution was degassed with nitrogen for 2 minutes. Pd(PPh3)4 (3.5 mg, 0.003 mmol) was added and the solution was degassed with nitrogen again for 2 minutes. The solution was sealed and placed in a microwave reactor. The wattage was set for 60 W until the temperature reached 150° C. and then the temperature was held at 150° C. for twenty minutes. The mixture was then cooled to room temperature, poured into H2O (10 mL), and extracted with EtOAc (30 mL). The organic layer was washed with brine (10 mL), dried over Na2SO4, filtered, and concentrated.
