Reaction Steps
18.2 g of carbon tetrabromide is added over 15 minutes at −15°/−20° C. to a mixture containing 11.2 g of the product of Stage A and 14.4 g of triphenylphosphine in 100 cm3 of methylene chloride. Agitation is carried out for 1 hour 15 minutes at −15° C., the solvent is evaporated off, followed by taking up in pentane, agitating at ambient temperature, separating, washing with pentane and drying at 50° C. under reduced pressure. 10.1 g of expected product is obtained.
