With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.822-82-2,Isothiazole-4-carboxylic acid,as a common compound, the synthetic route is as follows.
822-82-2, Isothiazole-4-carboxylic acid (0.65 g) is added portionwise to a stirred mixture of lithium aluminum hydride (0.19 g) in tetrahydrofuran (50 mL) at ambient temperature under nitrogen the reaction mixture is heated at reflux for 4 hours then cooled to 0 C. Sodium hydroxide solution (3% w/v) is added dropwise and the mixture stirred at 0 C. for 1 hour then filtered through hyflo. The filtrate is evaporated and azeotroped with toluene to give isothiazol-4-ylmethanol (0.35 g).
As the paragraph descriping shows that 822-82-2 is playing an increasingly important role.
