Procedure

A solution of Example 2A (0.33 g, 0.98 mmol), 4-(tert-butoxycarbonylamino)-3-fluorophenylboronic acid (0.25 g, 0.98 mmol), CsF (0.46 g, 3.0 mmol), and tetrakis(triphenylphosphine)palladium(0) (0.12 g, 0.098 mmol) in a solvent mixture of dimethoxyethane (2 mL) and methanol (1 mL) was heated to 90° C. for 16 h. The reaction was cooled to ambient temperature and diluted with ethyl acetate (5 mL) and H2O (5 mL). The layers were separated, and the organic was washed with 10% aqueous HCl (3×15 mL). 2N NaOH was added to the combined acidic aqueous layers until pH=8. The aqueous layer was extracted with ethyl acetate (3×15 mL). The extracts were then dried with anhydrous Na2SO4, filtered, and concentrated under reduced pressure to give the title product as a solid. MS (ESI) m/z 422 [M+H]+.
