실험 절차
By the method described in Example 1, 11.0 g (0.05 mol) of 2,3,4,5-tetrachloropyridine, 4.4 g (0.065 gram atom) of zinc dust (96.5%) and 24.7 g (0.135 mol) of the tetramethylammonium salt of methanephosphonic acid monomethyl ester in 90 ml of trimethyl phosphate are reacted to obtain 7.1 g (78% of theory) of 2,3,5-trichloropyridine, m.p. 47°-47.5° C., which contains, according to gas-chromatographical analysis, 97.6% of 2,3,5-trichloropyridine, 0.4% of 2,3,4,5-tetrachloropyridine and 1.4% of unknown products.
