With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.17402-83-4,Benzo[b]thiophen-4-amine,as a common compound, the synthetic route is as follows.
(Step 1) Diisopropylethylamine (0.10 ml) was added to a solution of ethyl 5-chloro-3-(methylthio)-1,2,4-triazine-6-carboxylate (70 mg) and benzo[b]thiophen-4-amine (70 mg) in THF (1 ml), and the reaction solution was stirred at room temperature for 35 minutes. The solvent was evaporated under vacuum, and then the resultant residue was purified by column chromatography on silica gel (developing solvent: hexane/ethyl acetate) to obtain ethyl 5-(benzo[b]thiophen-4-ylamino)-3-(methylthio)-1,2,4-triazine-6-carboxylate as a white solid.
17402-83-4, The synthetic route of 17402-83-4 has been constantly updated, and we look forward to future research findings.
