1423-61-6, 7-Bromobenzo[b]thiophene is a benzothiophene compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Preparation 109A: 4-(Benzo[b]thiophen-7-yl)isoquinoline[00356] A vessel capable of sealing was charged with a mixture of 7- bromobenzo[b]thiophene (430 mg, 2.018 mmol), isoquinolin-4-ylboronic acid (419 mg, 2.421 mmol), PdCl2(dppf)-CH2Ci2 adduct (82 mg, 0.101 mmol), dioxane (6 mL), and a 2.0 M aqueous solution of Kappa3RhoOmicron4 (3 mL, 1.41 mmol) and was purged with nitrogen for 10 min. The vessel was sealed and heated at 90 C for 16 hours. Upon cooling, the reaction mixture was diluted with CH2CI2 and filtered with CH2Cl2/MeOH washing. The filtrate was concentrated under reduced pressure. The residue was dissolved in CH2CI2 and washed with water, brine, dried over anhydrous a2S04 and concentrated under reduced pressure. The crude material was purified by BIOTAGE eluting with 0%-15% EtOAc/CH2Cl2 at 30 mL/min. Concentration of appropriate fractions provided the title compound (32 mg, 30% yield). LC/MS: Example 109A (at) 2.49 min (RT) (Condition G). MS (ES): m/z=262.42 [M+H]+. XH NMR (400 MHz, CDC13) delta ppm 9.38 (1 hr, s), 8.71 (1 hr, s), 8.08-8.15 (1 hr, m), 7.96 (1 hr, dd, J=8.06, 1.01 Hz), 7.51-7.71 (4 hr, m), 7.39-7.51 (3 hr, m)., 1423-61-6
As the paragraph descriping shows that 1423-61-6 is playing an increasingly important role.
