Reaction Steps

1-(4-bromophenyl)ethane-1,2-diol (0.15 g, 0.69 mmol) was dissolved in 7 mls of dry acetonitrile, followed by the addition of carbonyldiimidazole (0.17 g, 1.04 mmol). This mixture was warmed to 40° C. for 1.5 hours. After cooling to room temperature, the reaction mixture was diluted with EtOAc and washed with saturated ammonium chloride solution, water, dried over sodium sulfate and concentrated under reduced pressure. 10 g Sep Pak purification (1:1 EtOAc:Hexanes) afforded 0.095 g of 4-(4-bromophenyl)-1,3-dioxolan-2-one (57%) as a white solid.
