6314-28-9, Benzo[b]thiophene-2-carboxylic acid is a benzothiophene compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,6314-28-9
Reference Example 152 1-[(2-Benzothienylcarbonyl)amino]cyclohexanecarboxylic acid phenylmethyl ester Under ice-cooling, 5.9 g (31 mmol) of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride was added to a solution of 5 g (28 mmol) of 2-benzothiophenecarboxylic acid, 6.5 g (28 mmol) of 1-aminocyclohexanecarboxylic acid phenylmethyl ester and 4.5 g (29 mmol) of 1-hydroxybenzotriazole in methylene chloride. After the mixture was stirred at room temperature overnight, the reaction solvent was distilled off under reduced pressure. Water was added to the residue and the mixture was extracted with ethyl acetate twice. The obtained organic layer was washed with a 10% aqueous potassium hydrogensulfate solution, a saturated aqueous sodium hydrogencarbonate solution and then saturated brine, it was dried with anhydrous sodium sulfate. The solvent was distilled off under reduced pressure, diethyl ether was added to the obtained residue, and the mixture was stirred overnight. The crystal was collected by filtration and heated and dried under reduced pressure to obtain 10 g (91%) of the title compound. 1H-NMR (CDCl3, delta): 1.25-1.78 (6H, m), 1.93-2.05 (2H, m), 2.12-2.25 (2H, m), 5.18 (2H, s), 6.24 (1H, s), 7.20-7.38 (5H, m), 7.38-7.51 (2H, m), 7.77 (1H, s), 7.80-7.91 (2H, m)
As the paragraph descriping shows that 6314-28-9 is playing an increasingly important role.
