실험 절차

9,10-Dihydro-9,10-ethanoanthracene-11-methanol (1.2 gm), imidazole (0.7 gm) and chlorodiphenylphosphine (1.4 gm) were combined in toluene (80 ml) and treated dropwise with bromine (1.0 gm). The mixture was stirred 10 minutes, then extracted with 10% sodium hydroxide (50 ml) and water (50 ml). The toluene was removed on a rotary evaporator and the residue was dissolved in 1:1 methylene chloride/hexane and placed on a silica gel column. The column was eluted with 1:1 methylene chloride/hexane and the eluant removed on a rotary evaporator to give the product.
