Reaction Steps

5.5 g (0.0344 mol) liq. Bromine was added to a solution of 7.83 g (0.0658 mol) KBr dissolved in 100 mL water. Reaction mixture was heated to 60-65° C. and 5 g (0.0376 mmol) of 5-ethyl-2-vinyl-pyridine was added into it in 10 min. Reaction mixture was stirred for 30 min and quenched with excess of water. Product was extracted with dichloromethane, which was separated, dried, concentrated and purified to get 7.43 g (86%) of the titled product.
