Reaktionsschritte

2-(Furan-2-yl)-2-oxoacetic acid (15.0 g, 107 mmol) was dissolved in chloroform (420 mL) and treated with EtOH (165 mmol) and H2SO4 (1 mL). The reaction was heated to 65° C. overnight, at which point LC-MS indicated disappearance of starting material and product formation. The crude reaction was cooled and washed with sat. aq. NaHCO3 (3×100 mL) and brine (100 mL). The organics were concentrated to provide ethyl 2-(furan-2-yl)-2-oxoacetate (15.5 g, 64%) as a brown oil, which was used without further purification.
