Procedure
A solution of 120.14 g (0.80 mol) of 2-phenyl-1,3-dioxolane, 142.39 g (0.80 ml) of N-bromosuccinimide, 1 liter of carbon tetrachloride, and a catalytic amount of benzoyl peroxide was heated with stirring at reflux for 51/4 hours and cooled in accordance with the method disclosed in J. Org. Chem 43, 3418 (1978). The resulting mixture was filtered and the filtrate was concentrated and distilled. 147.8 g of product was collected; bp=104°-111° C./0.40 mm. (Rep. bp=90°-2° C./0.5 mm.)
