Analyzing the synthesis route of 42831-50-5

The synthetic route of 42831-50-5 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.42831-50-5,5-Methylisoxazole-4-carboxylic acid,as a common compound, the synthetic route is as follows.,42831-50-5

(iv) 5-Methylisoxazol-4-yl carbonyl chloride Thionyl chloride (118 g) was added to 5-methylisoxazol-4-yl carboxylic acid (42 g) and stirred at room temperature as dimethylformamide (0.2 ml) was added. The solution was heated under reflux for 2 hours with stirring. Excess thionyl chloride was removed in vacuo at 50 C., then the residue was distilled through a 15 cm Vigreaux column at reduced pressure to give an oil, b.p. 32-34 C./0.1 mm Hg.

The synthetic route of 42831-50-5 has been constantly updated, and we look forward to future research findings.
