Reaction Steps

To a stirred suspension of methyltriphenylphosphonium bromide (8.7 g, 24.35 mmol) and KOt-Bu (3.4 g, 30.3 mmol) in dry THF (20 mL), which was stirred at room temperature for 1 h under nitrogen, was added a solution of 4-(4-chloro-2,6-difluorophenoxy)benzaldehyde (5.4 g, 20.10 mmol) in THF (8 mL). The mixture was stirred at room temperature overnight, and quenched with water. The aqueous phase was extracted with DCM. The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated. Purification via flash chromatography afforded the title compound (2.6 g, 9.75 mmol, 48.5% yield). LCMS: rt=4.06 min, [M+H+]=267
