27.3 g was dissolved in 120 ml of chloroform, and a solution of 25.3 g of bromine dissolved in 30 ml of chloroform was added dropwise to this solution over 30 minutes under ice cooling. Thereafter, the mixture is stirred at room temperature for 1 hour to react. After washing the reaction product with a dilute aqueous sodium hydrogen carbonate solution and water, the organic layer is dried. The solvent is distilled off to obtain crude ethyl α-methoxyimino-β-keto-γ-bromobutyrate as an oil.
