Reaction Steps

Palladium tetrakis-triphenylphosphine (12 mg, 10 μmol) was added to a degassed solution of bromide 239 (46 mg, 0.2 mmol) and boronate 11 (88 mg, 0.4 mmol) in dioxane: acetonitrile:water (9:9:2, 1.5 mL) and potassium phosphate (63 mg, 0.3 mmol). The resulting mixture was heated under argon at 90° C. with stirring for 4 hours. The mixture was then cooled, extracted with dichloromethane (3×10 mL), dried with sodium sulfate and concentrated under reduced pressure. Flash chromatography (ISCO system, silica, 0-50% ethyl acetate in hexane) provided 240 (32 mg, 66%) as an oil: LRESIMS m/z 245.1 [M+H]+, calcd. for C14H17N2S1 245.1.
