With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.15864-32-1,2-Amino-6-bromobenzothiazole,as a common compound, the synthetic route is as follows.
15864-32-1, Step 6; To a solution of 2-amino-6-bromobenzothiazole (10 g, 0.044 mol) in dichloromethane (150 mL), DMAP (7 g) and acetic anhydride (18 g) were added. The solution was then refluxed overnight. The reaction mixture was concentrated, and then water was added thereto. The precipitate was collected by filtration, then washed with water and dried to yield target compound 50 (10.2 g, y. 85%).
As the paragraph descriping shows that 15864-32-1 is playing an increasingly important role.
