A mixture of 120.14 grams (0.80 mol) of 2-phenyl-1,3-dioxolane, 142.39 grams (0.80 mol) of N-bromosuccinimide, 1 liter of carbon tetrachloride and a catalytic amount of benzoyl peroxide was heated with stirring at reflux for 5.25 hours and then cooled. The mixture was filtered, and the filtrate was concentrated to an oil. Distillation of this oil gave 147.8 grams; (80.65% of theory) of the product; bp=104°-111° C./0.40 mm.
