반응 단계
Sodium 4-hydroxybutyrate (25 g, 0.2 mol) and benzyl bromide (37 g, 0.22 mol) were dissolved in a mixed solvent of DMF (40 ml) and ethyl acetate (50 ml), and the reaction mixture was heated and refluxed for 4 hours. Then, the reaction mixture was allowed to cool to room temperature, diluted with a proper amount of ethyl acetate, washed with saturated saline solution, dried over anhydrous sodium sulfate and concentrated under reduced pressure to give an oily product. The resulted product was purified by silica gel column chromatography (eluent:hexane/ethyl acetate=4/1) to give 34.9 g of benzyl 4-hydroxybutyrate. Yield: 90%.
