Brief introduction of 348-40-3

348-40-3, As the paragraph descriping shows that 348-40-3 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.348-40-3,6-Fluorobenzo[d]thiazol-2-amine,as a common compound, the synthetic route is as follows.

Hydrochloric acid (10 mL) was added dropwise to hydrazine hydrate 99% (10 g, 0.2 mol) at 5-10 C, followed by addition of a solution of 2-amino-6-fluorobenzothiazole (1) (3.364 g, 0.02 mol) in ethylene glycol (40 mL). The mixture was heated at reflux temperature for 5 h. On cooling, the precipitated solid was collected by filtration, washed with water, dried and crystallized from ethanol. Yield 89%, m.p. 194-196 C [1].
