Procedure
A solution of 12 milliliters of formic acid (97-100 percent) and 3.5 grams of 2-hydrazino-4,5-dimethylbenzothiazole was refluxed for 24 hours with stirring. The reaction mixture was then cooled to room temperature and poured into water. The 5,6-dimethyl-s-triazole(3,4-b)benzothiazole compound precipitated and was separated by filtration, 2.6 grams, m.p. 226-8° C.
