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.
General procedure: NEt3 (0.57?mL, 4.00?mmol) was added dropwise to a suspension of 3-methoxyphenylacetic acid (0.60?g, 4.00?mmol) and [Ti(eta5-C5H5)2Cl2] (0.50?g, 2.00?mmol) in toluene (50?mL) at room temperature. The reaction mixture colour changed immediately from deep red to orange and was then stirred for 3?h at 80?¡ãC. The mixture was decanted and filtered to remove the triethylammonium chloride salt. The filtrate was then concentrated and cooled to ?30?¡ãC to give orange crystals of the complex which were isolated by filtration.
4442-54-0, The synthetic route of 4442-54-0 has been constantly updated, and we look forward to future research findings.
