Procedure
5,6-Dimethyl-2-aminobenzothiazole (5.0 g., 0.028 mole), 85% hydrazine hydrate (3.49 g.; 0.056 mole) and hydrazine monohydrochloride (1.99 g.; 0.028 mole) were reacted in the procedures of Example 1. 5,6-Dimethyl-2-hydrazinobenzothiazole was obtained in 82% yield, m.p. 223°-228°C. Assay (titration) 97.2%. Recrystallization from ethanol gave material melting 235°-237°C. (dec.).
