677304-75-5, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 6-Bromobenzo[d]isothiazole-3-carboxylic acid, cas is 677304-75-5,the isothiazole compound, it is a common compound, a new synthetic route is introduced below.
Step 5; Sulfuryl dichloride (86.7 mg, 728 mumol) is added to a solution of6-bromobenzo[d]-isothiazole-3-carboxylic acid (188 mg, 728 mumol). The reaction mixture is stirred for 30 min before removing the volatiles by rotovap. The residue is taken up in CH2Cl2 (0.587 ml) and a solution of 2-prorhoylamine (62.5 muL, 728 mumol) and triethylamine (101 mul, 728 mumol) in CHjCl2 (1.2 ml) is added. The reaction mixture is stirred at room temperature until LC/MS analysis indicates complete conversion to the desired product. The reaction mixture is diluted with distilled water and ethyl acetate. The layers are separated and the aqueous is extracted with ethyl acetate. The combined organics are washed with brine and dried over Na2SO4, filtered and concentrated to give 6-bromo-N-isopropylbenzo[d]isothiazole- 3-carboxamide.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 677304-75-5, 6-Bromobenzo[d]isothiazole-3-carboxylic acid
