With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.20699-86-9,Methyl 5-nitrobenzo[b]thiophene-2-carboxylate,as a common compound, the synthetic route is as follows.
To the above product 6-Nitro-benzo[b]thiophene-2-carboxylic acid methyl ester (1 g, 0.004 mol) and SnCI2-H2O (4.85 g, 0.017 mol) was added concentrated HCI (20 ml_, 0.24 mol). The reaction was stirred at 80 0C for 1 hour, then cooled to low temperature. Then, the pH of the reaction mixture was raised to pH = 9 ~ 11 using 10% NaOH solution in water. The suspension was then filtered and residue was washed with H2O followed by CH3OH to yield the product as yellow solid quantitatively., 20699-86-9
20699-86-9 Methyl 5-nitrobenzo[b]thiophene-2-carboxylate 1489057, abenzothiophene compound, is more and more widely used in various.
