Participants

Reaction Steps

0.024 mmol of tetrakis(triphenylphosphine)palladium, 12.3 mmol of 2-furanboronic acid and 7.5 ml of 2 M sodium carbonate solution are added to a solution of 6.15 mmol of ethyl (2S)-2-(4-bromophenoxy)-4-phenylbutanoate in 25 ml of dimethoxyethane. The mixture is refluxed for 2 hours. After cooling to room temperature, the mixture is taken up in water and extracted with ethyl acetate. The organic phase is dried over sodium sulfate (Na2SO4) and then evaporated to dryness under vacuum. 2.6 g of a brown oil are obtained. This oil is chromatographed with a 9/1 heptane/ethyl acetate mixture as eluent. 1.5 g of an oil that crystallizes are obtained.
