Reaction Steps
0.45 mL of sulfuric acid was added to ethanol (70 mL) solution of 7.0 g of (R)-2-bromobutyric acid at room temperature, and refluxed for 3 hours. The reaction mixture was cooled to room temperature, and poured into ice water (140 mL). The solution was extracted 3 times with ethyl acetate. The combined extract was sequentially washed with saturated sodium hydrogen carbonate solution and brine, and dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated in vacuo, and 7.47 g of the subject compound was prepared as colorless oil. Optical purity 96% ee (HPLC)
