Preparation Method
In a reaction bottle equipped with a stirrer, thermometer and vent tube, 200 g (2.33 mol) of γ -butyrolactone and 375mL of anhydrous ethanol were added, cooled to 0ºC in an ice salt bath, and dried hydrogen bromide gas was introduced until the reactants remained unchanged, which took about 2 hours. Leave it at 0ºC for 24h. Pour the reactant into 1L cold water, fully stir, separate the organic layer, and extract the water layer with bromoethane twice, 10mL each time. Combining organic layers, washing ethanol with 2% potassium hydroxide solution, dilute hydrochloric acid and water, drying with anhydrous sodium sulfate, recovering solvent, vacuum fractionating, and collecting fractions at 97 ~ 99ºC/3.3 kPa to obtain 350 ~ 380 g of ethyl γ-bromobutyrate (1) with a yield of 77% ~ 84%.

Uses
Ethyl 4- bromobutyrate is a carboxylate derivative, which is colorless, transparent to yellow liquid. It can be used as an intermediate of pesticides and medicines, and can be used in laboratory research and development and chemical production.
