Reaction Steps

In a flask with a water separator, a mixture of 11.02 g of benzoylformic acid (glyoxalic acid), 6.62 g of 3-buten-1-ol and 0.42 g of p-toluenesulfonic acid in 130 ml of toluene is heated at 110° C. for 22 hours. The solution is washed with saturated NaHCO3 solution and water. The organic phases are dried over sodium sulfate. Filtration, evaporation of the solvent and distillation (b.p.=85° C. at 0.035 mbar) give but-3-enyl glyoxalate (8.08 g, 54%) as a pale yellowish liquid.
