With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.6314-28-9,Benzo[b]thiophene-2-carboxylic acid,as a common compound, the synthetic route is as follows.
6314-28-9, Benzo[Z>]thiophen-2-yl-carbamic acid tert-butyl ester (1-B).; A solution of compound 1-A (14.4 g, 80.6 mmol), N,N-diisopropylethylamine (15.5 mL, 88.6 mmol) and diphenylphosphoryl azide (20.8 mL, 96.7 mmol) in -butanol (150 mL) was heated at reflux for 8 h. The solvent was evaporated in vacuo, and the residue purified by flash column chromatography on silica gel, eluting with dichloromethane, to afford compound 1-B as a colorless solid (18.9 g, 94%). 1H-NMR (DMSO-^): delta 1.50 (s, 9H),
6314-28-9 Benzo[b]thiophene-2-carboxylic acid 95864, abenzothiophene compound, is more and more widely used in various fields.
