반응 단계
Combine 10.1 g (0.1 mole) 5-amino-1,2,3-thiadiazole, 75 ml of tetrahydrofurane and 11.5 ml (0.106 mole) of phenyl isocyanate. Further add 0.1 ml of triethylamine as catalyst. After standing overnight, the first crystals will have precipitated. The solvent is removed by evaporation under vacuum, and the residue is recrystallized from isopropanol.
