Dimethylformamide → 4-(Bromomethyl)-5-methyl-1,3-dioxol-2-one

To 403 mg of 4-(chloromethyl)-5-methyl-1,3-dioxol-2-one and 525 mg of sodium bromide was added 0.8 ml of anhydrous N,N-dimethylformamide, followed by at room temperature for 1.5 hours. To the reaction solution was added 1.2 ml anhydrous acetone, the mixture was further stirred at room temperature for 1 hour, and then insolubles were removed by filtration. Insolubles were washed three times with 0.8 ml of anhydrous acetone, and the resulting pale yellow solution was used in the next reaction.
