Procedure
A mixture of 29.8 g of 2-chloro-6-isopropenylpyridine, 29.8 g of N-chlorosuccinimide and 60 ml of benzene was stirred at 80° C. for 5 hours. After the reaction mixture was cooled to room temperature, 200 ml of n-hexane was added thereto to remove the insoluble matter through filtration. After distilling off the solvent, the residue was purified by silica gel column chromatography (eluted with n-hexane then n-hexane - ethyl acetate 20:1) to obtain 20.6 g of the objective compound.
