360575-29-7, Methyl 4-bromobenzo[b]thiophene-2-carboxylate is a benzothiophene compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
12151] A mixture of 750 ng of methyl 4-bromobenzo[b] thiophene-2-carboxylate, 438mg of phenyl boronic acid, 610 mg of lithium chloride, 528mg of sodium carbonate, 160mg of tetrakis(triphenylphosphine)palladium (0), 30 ml of 1,4- dioxane, and 15 ml of water was stirred for 4 hours at 1000 C. under nitrogen atmosphere. After being cooled to room temperature, the reaction mixture was concentrated under reduced pressure. Chloroform and water were added to the residues, and insoluble matter was separated by filtration. The aqueous layer was extracted twice by using chloroform, and the collected organic layer was washed with saturated saline, dried over magnesium sulfate, and then concentrated under reduced pressure. The residues were subjected to silica gel column chromatography, thereby obtaining 477mg of methyl 4-phenylbenzo[b]thiophene-2-carboxylate (hereinafier, described as a ?compound 34 of the present invention?).12152] Compound 34 of the Present Inventionj2153] ?H-NMR (CDC13) oe: 8.17-8.16 (m, 1H), 7.87-7.85 (m, 1H), 7.57-7.48 (m, 5H), 7.47-7.42 (m, 1H), 7.41-7.39 (m, 1H), 3.93 (s, 3H)., 360575-29-7
The synthetic route of 360575-29-7 has been constantly updated, and we look forward to future research findings.
