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.
WORKING EXAMPLE 17 A mixture of 1,4-benzodioxane-6-carboxylic acid (0.5 g), benzene (20 ml) and thionyl chloride (5 ml) is heated for one hour under reflux. The reaction mixture is evaporated to dryness under reduced pressure. To the residue is added benzene (50 ml), then the solvent is again distilled off to leave 1,4-benzodioxane-6-carbonyl chloride.
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.
