実験手順

A mixture of compound 39 (4.25 g, 0.-22 mol), bromine (12.31 g, 0.077 mol was then added and heating continued for another 24 h. The resultant solution was washed with a saturated solution of sodium thiosulphate and finally with water. The dichloromethane solution was dried (MgSO4) and evaporated in vacuo and the crude oil was purified by column chromatography (10% petrol/dichloromethane) to yield a fawn oil.
