Reaction Steps

Compound 20-1 (9.39 g) was dissolved in diethyl ether (100 ml), phosphorus tribromide (8.58 ml) was added under ice-cooling, and the mixture was stirred under ice-cooling for 3.5 hr. To the reaction mixture was slowly added water, and the mixture was extracted with diethyl ether. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to give the object product (4.93 g) as a pale-yellow oil.
