With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4442-54-0,2,3-Dihydro-1,4-benzodioxine-6-carboxylic acid,as a common compound, the synthetic route is as follows.
A mixture of 2,3-dihydrobenzo[b][1,4]dioxine-6-carboxylic acid (1 mmol) with concentrated sulfuric acid (0.5 mL) in methanol(30 mL) was heated at 65¡ãC overnight. The solvent was removed in vacuo, the oil was dissolved in ethyl acetate (20 mL) and extracted with water (40 mL). After drying the organic layer with anhydrous Na2SO4and evaporating the solvent under reduced pressure asolid precipitate was formed. It was recrystallized fromethanol., 4442-54-0
4442-54-0 2,3-Dihydro-1,4-benzodioxine-6-carboxylic acid 2758833, abenzodioxans compound, is more and more widely used in various fields.
