With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.119256-40-5,4,6-Difluorobenzothiazol-2-ylamine,as a common compound, the synthetic route is as follows.
EXAMPLE 5 5-Methyl-thiophene-2-carboxylic acid (4.6-difluoro-benzothiazol-2-yl)-amide Using 2-amino-4,6-difluoro-benzothiazole and 5-methyl-thiophene-carboxylicacid chloride the title compound was prepared as a yellow solid (74% yield), MS: m/e=310 (M+).
As the paragraph descriping shows that 119256-40-5 is playing an increasingly important role.
