Reaction Steps

To a solution at −5° C., of 50 g (0.3759 mol) 5-ethyl-2-vinyl-pyridine dissolved in a mixture of 2504 mL dimethylsulfoxide and 13.5 my water was added 99.3 g (0.5578 mole) N-bromosuccinimide and stirring was continued for 30 min. at 0 to −5° C. Reaction mixture was quenched with 2500 mL water and the product was extracted with dichloromethane. Organic layer was dried (calcium chloride); concentrated and purified to get the desired product. Yield of the product was 76.09 g (88%). The two side products in this reaction found were 2-acetyl-5-ethyl-pyridine (5%) and 2-(1-bromo vinyl)-5-ethyl-pyridine (6%).
