Reaction Conditions

Reaction Steps

To a stirred solution of 66.46E (555 mg, 1.52 mmol) in DMF (10 mL) at 23° C. was added 2-fluoro-5-methoxyphenylboronic acid (512.3 mg, 3.0 mmol) (commercially available from Aldrich) and potassium carbonate (630.1 mg, 4.56 mmol) followed by tetrakis(triphenylphosphine)palladium(0) (176.8 mg, 0.15 mmol). The mixture was heated to 90° C. After 18 hours, LCMS showed the reaction was complete. The mixture was cooled to room temperature and diluted with water. After extracting three times with EtOAc, the mixture was concentrated in vacuo, and the residue was purified on silica gel (0-50% EtOAc in hexanes) to afford 66.46F (452.7 mg, 87% yield). MS ESI (pos.) m/e: 343.0 (M+H)+.
