Pd(dppf)CI2 DCM (32 mg, 0.04 mmol) was added followed by 1.8 M K2C03 (1.74 mL, 3.12 mmol). The reaction mixture was heated at reflux for 2 hours then cooled to room temperature, diluted with EtOAc (50 mL) and washed with water (2 χ 25 mL). The combined aqueous phases were back-extracted with EtOAc (50 mL). The combined organics were washed with brine (50 mL) then concentrated in vacuo and purified by fee (0-100% EtOAc in isohexane) to return the title compound (438 mg, 80%) as a yellow solid.
