실험 절차
Following the procedure of Example 5, 6.4 g. of 2-amino-3-chloropyridine, 11 g. of calcium carbonate and 6.3 g. of thiophosgene is converted into 3-chloro-2-pyridylisothiocyanate b.p. 86° C. at 0.25 mm. of Hg. Upon standing overnight, the freshly distilled 3-chloro-2-pyridylisothiocyanate solidifies affording 9-chloro-3-(3-chloro-2-pyridyl) pyrido (1,2-a) 1,3,5-triazine-2,4-dithione m.p. 120°-122° C.
