Participants

Reaction Steps

A solution of 6.1 grams of 2-hydrazino-4-methylbenzothiazole (0.034 mole) and 6.4 grams of triethyl orthoacetate (0.04 mole) in 200 milliliters of xylene was brought to reflux temperature over a period of 5 hours and thereafter refluxed for 96 hours. The reaction mixture was then concentrated to one-fourth of the original volume and allowed to cool to room temperature. The 3,5-dimethyl-s-triazolo(3,4-b)benzothiazole product was separated by filtration, 4 grams, m.p., 196°-8° C.
