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%) and 4.0 g (0.075 mol) of ammonium chloride are reacted to yield 7.1 g (78% of theory) of 2,3,5-trichloropyridine, m.p. 36°-40° C., which contains, according to gas-chromatographical analysis, 79.2% of 2,3,5-trichloropyridine, 11.8% of 2,3,4,5-tetrachloropyridine and 6.6% of unknown products.
