Reaction Conditions

Reaction Steps

L-Tartaric acid diethyl ester (10.0 g), acetic acid (100 ml), N-bromosuccinimide (34.5 g) and 2,2′-azobis(4-methoxy-2,4-dimethylvaleronitrile) (0.15 g) were mixed, and the reaction solution was stirred at 55° C. for 3 hours. The reaction solution was concentrated under reduced pressure until its volume became 50 ml to afford a solution of diethyl dioxobutanedioate in acetic acid as a yellow liquid.
