実験手順

The 2-oxo-butyric acid ethyl ester prepared above was dissolved in chloroform (100 mL) and bromine (20.964 g, 131.19 mmol) was added dropwise at room temperature. The reaction mixture was allowed to stir for 18 h. Concentration of the reaction mixture under reduced pressure provided 12.0 g of the title compound as an orange oil. 1H NMR (CDCl3) δ 4.39 (q, 2H), 4.32 (q, 1H), 1.88 (d, 3H), 1.39 (t, 3H).
