Acetic Acid → 2-Hydrazinyl-4,6-dinitro-1,3-benzothiazole

Participants

Reaction Steps

24.0 g of amino-4,6-dinitrobenzthiazole are heated to boiling for 1 hour in 200 ml of 2-ethoxyethanol with 20 ml of hydrazine hydrate (100% purity). After cooling to room temperature, the reaction mixture is poured into a mixture of 750 ml of water and 20 ml of glacial acetic acid, stirred for 1 hour, filtered off under suction, washed with water and dried. 21.0 g of 2-hydrazino-4,6-dinitrobenzthiazole are obtained. Melting point 210°-214° C. (decomposition). After recrystallization from 2-methoxyethanol. Melting point 216°-217° C. (decomposition).
