As a common heterocyclic compound, it belongs to benzodioxans compound, name is 2,3-Dihydro-1,4-benzodioxine-6-carboxylic acid, and cas is 4442-54-0, its synthesis route is as follows.,4442-54-0
A solution of 19.6 g (109 mmol) of 2,3-dihydro-benzo[1,4]dioxine-6-carboxylic acid (J. Chem. Soc., 3445, 1957) in 400 mL of MeOH containing 4 mL of H2SO4 was refluxed overnight. Sodium bicarbonate (18 g) was added, the solvent was removed and the residue was triturated several times with Et2O. The washes were combined, filtered through anhyd MgSO4 and evaporated to yield 20.7 g of the title compound as a pale yellow oil: mass spectrum (electron impact, m/e): 194.
With the complex challenges of chemical substances, we look forward to future research findings about 4442-54-0,belong benzodioxans compound
