(2S)-2-bromobutanedioate - Production method
From the bromination of fumarate. After adding 40% hydrobromic acid to fumaric acid, it is saturated with hydrogen bromide gas, and then kept in an oil bath at 105-130 ℃ for 6 hours to obtain crude product; after dissolving in water, it is extracted with ether; after diethyl ether is recovered, white crystals are obtained, then dissolved in water, filtered, concentrated under reduced pressure to obtain crystals, and washed with ethyl acetate to obtain finished products.
