Procedure

To a mixture of 750 mL tert-butanol and 2250 mL water, 200 g (1.488 mol) of 5-ethyl-2-vinyl-pyridine was dissolved and under stirring 324 g (1.786 mol) N-bromosuccinimide was added in 30 min. at 25-30° C. Stirring was continued for 1 hr. and 178.6 g (4.46 mol) of NaOH dissolved in 2250 mL water was added into it. Reaction mixture was stirred for 45 min. Product was extracted twice with 1100 mL methyl tert-butyl ether. Organic layers were combined, washed with brine, dried over magnesium sulfate and concentrated in vacuo to yield 206.13 g (92%) of 6.
