With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.32137-76-1,Ethyl 1,3-benzothiazole-2-carboxylate,as a common compound, the synthetic route is as follows.
To a 250 mL round bottom flask was added ethyl benzothiazole-2-carboxylate (1.0363 g, 5.0 mmol). 20 mL ethanol and 2 mL hydrazine hydrate were added followed by heating the solution to reflux for 6 hours. The reaction mixture was cooled to room temperature and solid precipitate was filtered, collected, and recrystallized in ethanol to yield benzo[d]thiazole-2-carbohydrazide (943.4 mg, 89.1% yield).
32137-76-1, The synthetic route of 32137-76-1 has been constantly updated, and we look forward to future research findings.
