With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.20197-75-5,Methyl 1,4-Benzodioxan-6-carboxylate,as a common compound, the synthetic route is as follows.,20197-75-5
Protocatechuic acid (0.0973 mol, 15 g) was dissolved in methanol (100 ml) with stirring,catalyzed by concentrated sulfuric acid. The mixture was stirred for about 20 h at 63C and evaporated. The concentratedsolution was poured into 200 ml of ethyl acetate and 100 ml of water and stilled. The ethyl acetate solvent was evaporated togive white powdered compound 1.Compound 1 (0.06 mol, 10.0824 g) and 1,2-dibromoethane (0.12 mol, 10.45 ml) were dissolved in acetone (100 ml)with stirring, using K2CO3 (0.24 mol, 33.16 g) as the acid binding agent. The mixture was stirred for about 24 h at 56C. Theinsoluble substance was removed by filtration; the solvent was evaporated to obtain yellow powdered compound 2.A mixture of compound 2 (0.01 mol, 1.9406 g) and hydrazine hydrate (0.064 mol, 3.1 ml) in ethanol (200 ml) wasstirred at 80C for 24 h. The solvent was evaporated to gain white powdered compound 3.
The synthetic route of 20197-75-5 has been constantly updated, and we look forward to future research findings.
