154650-81-4, Benzo[b]thiophene-6-carbonitrile is a benzothiophene compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

General procedure: Substituted benzothiophene (1 eq.) was dissolved in 1,2-dichloroethane. A solution of bromine(1.12 eq.) in 1,2-dichloroethane (CH2Cl2 for 17) was slowly added to the reaction mixture at 0 C, thenwarmed to r.t., and stirred for 2 h. Reaction progress was monitored by thin-layer chromatography(TLC, reverse phase silica gel, MeOH). Aqueous Na2S2O3 solution was added, and the desired productwas extracted with CH2Cl2. Combined organic layers were washed with brine, and dried overanhydrous Na2SO4. After filtration, the solvent was removed under reduced pressure. The productwas purified using column chromatography.

Analyzing the synthesis route of 154650-81-4

154650-81-4 Benzo[b]thiophene-6-carbonitrile 21816574, abenzothiophene compound, is more and more widely used in various.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.154650-81-4,Benzo[b]thiophene-6-carbonitrile,as a common compound, the synthetic route is as follows.

[0167] Compound 23 (14 g, 0.088 mol) in dry THF (350 mL) was purged with nitrogen. The mixture was then cooled (-90 0C) with liquid nitrogen bath and ra-BuLi (2.5 M in hexanes, 42 niL, 0.105 mol) was added dropwise with stirred. The mixture was stirred for a further 30 min, and B(OMe)3 (18 g, 0.173 mol) was added at -90 0C. After 30 min, aqueous HCl (2M, 200 mL) was added. The mixture was stirred for a further 30 min, allowed to warm to room temperature (30 0C), poured into water (100 mL). The mixture was extracted with EtOAc (400 mLx3). The combined organic layers were washed with water, brine, dried over Na2SO4 and concentrated to give a crude product, which was crystallized with EtOAc/PE (1:2, 100 mL) to give the title compound (12 g, 72%) as a white solid.
