反応手順
A stirred solution of 3.9 grams of mucochloric acid in water is warmed to 8°-100° C., and a mixture of 3.1 grams of hydrazine sulfate and 3.0 grams of sodium acetate is added. A solid is collected by filtration and recrystallized from water to yield 3.0 grams of 4,5-dichloro-3-pyridazone; m.p. 199°-200° C. The reaction is repeated several times.
