Reaction Steps

Palladium tetrakis-triphenylphosphine (68 mg, 0.1 mmol) was added to a degassed solution of bromide 244 (250 mg, 1.2 mmol) and boronate 11 (521 mg, 2.4 mmol) in dioxane:acetonitrile:water (9:9:2, 6 mL) and potassium phosphate (376 mg, 1.8 mmol). The resulting mixture was heated under argon at 90° C. with stirring for 18 hours. The mixture was then cooled, extracted with dichloromethane (3×15 mL), dried with sodium sulfate and concentrated under reduced pressure. Flash chromatography (ISCO system, silica, 0-50% ethyl acetate in hexane) provided 245 (202 mg, 76%) as an solid: LRESIMS m/z 225.2 [M+H]+, calcd. for C14H13N2O1 225.1.
