Reaction Steps

3.0 g of 4-pyridinepropanol was dissolved in 90 ml of chloroform, 9.4 g of carbon tetrabromide and 7.5 g of triphenylphosphine was added under ice cooling, and the mixture was stirred for 2 hours. Ether was added to the reaction solution, and the mixture was extracted with 1N hydrochloric acid, and then the aqueous layer was washed with ether. The aqueous layer was adjusted to be basic with 6N sodium hydroxide, and extracted with ether. The organic layer was dried over anhydrous magnesium sulfate, and filtered. The filtrate was evaporated under reduced pressure to give 4.86 g of 4-(3-bromopropyl)pyridine.
