Reaction Steps

In a 10 mL round-bottom flask, 1.58 g of ethyl 2-acetylbutyrate (10 mmol), 2.1 g bromotrichloromethane (10.5 mmol), and 200 mg of tetra-n-butylammonium fluoride trihydrate (0.632 mmol) were mixed at 24° C. for 1 h. Gas chromatographic analysis of the resulting mixture showed the presence of 1.34 g of ethyl 2-acetyl-2-bromobutyrate (56% yield).
