実験手順
The 2,4,4-trichloro-4-formyl-butyronitrile (17.3 g) obtained according to (a) is heated, as a weak stream of hydrogen chloride is being introduced, at 80°-85° C. for 24 hours. The entire reaction mixture is subsequently distilled with steam. The yield is 10.0 g (72% of theory) of 2,3,5-trichloropyridine in the form of white crystals, m.p. 49°-50° C.
