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.
2,3-Dihydrobenzo[b][1,4]dioxine-6-carboxylic acid (1 mmol) in methanol (30 ml) was treated with concentrated sulfuric acid (0.5 ml) under reflux overnight. The sovlent was removed in vacuo leaving oil which was dissovled in ethyl acetate (20 ml) and extracted with water (40 ml). After drying the organic layer with anhydrous Na2SO4 and evaporating the solvent under reduced pressure and a solid appeared. The solid was recyrstallized from ethanol to obtain the compound 1., 4442-54-0
The synthetic route of 4442-54-0 has been constantly updated, and we look forward to future research findings.
