실험 절차

Instead of isolating the 2-chloro-5-(trichloromethyl)-pyridine from this mixture, the above-described mixture is reacted with chlorine according to the conditions of the present invention as described herein to form 2,3-dichloro-5-(trichloromethyl)pyridine. The resulting 2,3-dichloro-5-(trichloromethyl)pyridine is separated from the reaction mixture by distillation, crystal refining, recrystallization from a solvent or a combination thereof.
