Reaction Steps

7.0 g of 5-hydroxypentyl benzyl ether and 10.6 g of triphenylphosphine were added to 50 ml of methyl tert-butyl ether and then cooled to 0° C. Further, 13.2 g of carbon tetrabromide was added and the mixture was stirred at room temperature for 3 hours. Thereafter, 100 ml of hexane was added and the mixture was concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to obtain 5.5 g of 5-bromopentyl benzyl ether.
