反応手順
The product from (b) (64 g) in dry carbon tetrachloride (650 ml) was treated with dry hydrogen chloride. The precipitate was broken up and the suspension heated under reflux while dry chlorine was bubbled into the mixture, with illumination from an ultra-violet light source. After 41/2 hours, the mixture was cooled, filtered, and the filtrate evaporated to give the required 2,3-dichloro-5-trichloromethylpyridine. The mass spectrum was consistent with the structure assigned to this compound.
