실험 절차

A microwave vial was charged with 7-(benzylthio)-4-chloroquinazoline (0.372 g, 1.298 mmol), (2-chloro-3′-fluoro-5-methoxy-[1,1′-biphenyl]-4-yl)boronic acid (0.364 g, 1.298 mmol), tetrakis(triphenylphosphine)palladium(0) (0.150 g, 0.130 mmol), and potassium carbonate (0.897 g, 6.49 mmol). Dioxane (3.24 ml) and Water (1.081 ml) were added; the vial was flushed with argon and sealed, and microwaved at 90° C. for 30 minutes. The reaction was diluted with ethyl acetate and washed with water. The aqueous layer was extracted with ethyl acetate, and the combined organic layers were dried with sodium sulfate, filtered, and concentrated. The material was purified via column chromatography (RediSep Gold 12 g, gradient elution 0-75% EtOAc:Heptane) to afford 7-(benzylthio)-4-(2-chloro-3′-fluoro-5-methoxy-[1,1′-biphenyl]-4-yl)quinazoline as a yellow solid. (ESI) 487.1 (M+H)+.
