Participants

Reaction Steps

A mixture of Example 220C (750.0 mg, 1.409 mmol), (2,3-difluorophenyl)boronic acid (267 mg, 1.690 mmol), bis(triphenylphosphine)palladium(II)dichloride (39.5 mg, 0.056 mmol), and 1M sodium carbonate (1409 μL, 1.409 mmol) in 10 mL 1,2-dimethoxyethane/ethanol/water (7:2:3) was heated in a Biotage Initiator microwave reactor at 150° C. for 15 minutes. The mixture was concentrated, treated with ethyl acetate and washed with aqueous sodium bicarbonate. The organic layer was washed with water, dried over magnesium sulfate, filtered, concentrated and purified on silica gel using an ISCO Companion eluting with heptanes/ethyl acetate (7:3 to 6:4) to give the title compound. MS (ESI+) m/z 566.1 (M+H)+.
