반응 단계
A solution of 1.38 g of 2-bromo-3',4'-dihydroxy-5'-nitroacetophenone and 461 mg of thiosemicarbazide in 20 ml of n-butanol is heated to boiling under reflux for 60 minutes. After cooling to room temperature the crystals are filtered under suction and recrystallized from n-butanol. There is obtained 5-(2-amino-6H-1,3,4-thiadiazin-5-yl)-3-nitropyrocatechol hydrobromide of m.p. 265°-267°.
