4923-87-9, 5-Bromobenzothiophene is a benzothiophene compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
5-bromobenzo[b]thiophene (3.0 g, 14.08 mmol) and 4-hydroxyphenylboronic acid (2.91 g, 21.11 mmol) were dissolved in DME 40 mL. Water 10 mL was added thereto. Pd(dbpf)Cl2 (459 mg, 0.70 mmol) and Cs2CO3 (13.68 g, 42.24 mmol) were added thereto, and refluxed with heating at 90 C. for a day. The reaction mixture was filtered through Celite. The obtained filtrate was extracted with EtOAc three times, dried over MgSO4, and then concentrated under reduced pressure. The obtained concentrate was purified by silica gel column chromatography (15-20% EtOAchexane) to yield the title compound as white solid (2.30 g, 72%)
4923-87-9 5-Bromobenzothiophene 2776578, abenzothiophene compound, is more and more widely used in various.
