Procedure

A mixture of 5.0 g (28.4 mmole) of 4,4,6-trimethylchroman, 5.55 g of purified N-bromosuccinimide and 200 ml of carbon tetrachloride was heated under reflux for 12 hours. The succinimide was removed by filtration and the solvent was removed by evaporation in vacuo to give the title compound as a light yellow oil.
