Reaction Steps

A solution of 2-benzyl-2,3-dihydrobenzofuran (1.9 g, 9 mmole) in 25 ml carbon tetrachloride was cooled to 0° C. and a solution of 0.46 ml (9 mmole) bromine in 5 ml carbon tetrachloride was added at 0° C. The mixture was warmed to room temperature, washed with water, sodium bicarbonate solution, and water again. The solvent was then evaporated to afford 2.5 g of crude product which was purified by column chromatography on silica gel, eluting with hexane to afford 1.0 g (38.5%) of the desired compound, m.p. 70°-72° C.
