Reaction Conditions

Reaction Steps

A solution of Example 24A (0.750 g, 2/04 mmol), CsF (0.930 g, 6.12 mmol), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (0.447 g, 2.04 mmol), and tetrakis(triphenylphosphine)palladium(0) (0.231 g, 0.200 mmol) in a solvent mixture of dimethoxyethane (5 mL) and methanol (5 mL) was heated to 90° C. for 16 h. The reaction was cooled to room temperature and partitioned between H2O (10 mL) and ethyl acetate (10 mL). The layers were separated, and the aqueous was extracted with additional ethyl acetate (2×10 mL). The combined organics were dried with anhydrous Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified by chromatography on SiO2 gel, eluting with a gradient of 10% ethyl acetate in hexane to 50% ethyl acetate in hexane, to give the title compound. MS (ESI) m/z 319 [M+H]+.
