D. 1-[(3,3-Dimethyl-3-silabutoxy)methyl]-5-(6-isoquinolyl)-2-(phenylsulfonyl)imidazole. To a solution of 6-bromoisoquinoline (73 mg, 0.35 mmol) in anhydrous DMF (0.75 mL) was added copper(II) oxide (28 mg, 0.35 mmol). The mixture was purged with nitrogen, tetrakis(triphenylphosphine)palladium(0) (55 mg, 0.048 mmol) was added, and then the materials were stirred at 100 C. for 5 minutes in a sealed vial. The vial was cooled to room temperature and then a solution of 5-(1,1-dibutyl-1-stannapentyl)-1-[(3,3-dimethyl-3-silabutoxy)methyl]-2-(phenylsulfonyl)imidazole (200 mg, 0.3.19 mmol) in anhydrous DMF (0.25 mL) was added. The mixture was purged with nitrogen then the sealed reaction was stirred at 105 C. for 8 hours. The reaction was cooled to room temperature, filtered through celite, and the celite rinsed with ethyl acetate. The filtrate was diluted with water, extracted three times with dichloromethane, and the organic layers combined. The organic solution was washed with brine, dried over anhydrous magnesium sulfate, filtered, and volatiles evaporated. The material was purified by chromatography on a normal phase silica gel column with 30 to 100% ethyl acetate in hexanes. Fractions containing clean product were combined and the solvent evaporated. The material was dried under vacuum at 60 C. to provide the title compound (1.2 g, 87%). MS (ESI) m/z 466.2 [M+1]+.

Analyzing the synthesis route of 34784-05-9

34784-05-9 6-Bromoisoquinoline 313681, aisoquinoline 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.34784-05-9,6-Bromoisoquinoline,as a common compound, the synthetic route is as follows.

[00309] 6-(4-Nitro-lH-pyrazol-l-yl)isoquinoline: A mixture of 4-nitro-lH- pyrazole (510 mg, 4.51 mmol), 6-bromoisoquinoline (375 mg, 1.80 mmol)(commercially available from Gateway Chemical Technology, Inc.), tris(dibenzylideneacetone)dipalladium (0) (165 mg, 180 mumol), 2-ditert-butylphosphino- 2′,4′,6′-triisopropyl-l,r-biphenyl (153 mg, 360 mumol), and cesium carbonate (1.76 g, 5.41 mmol) in dioxane (4 mL) was heated in a sealed vial at 105C for 6 hours. The mixture was cooled to ambient temperature and partitioned between DCM (30 mL) and H2O (30 mL). The layers were separated, and the aqueous layer was extracted with DCM (2 x 20 mL) and 10% MeOH/DCM (30 mL). The combined organic layers were dried (MgSO4) and concentrated under reduced pressure. The resulting yellow solid was dissolved in DCM, evaporated onto silica gel, and purified by flash chromatography (Biotage Si 40+M, 20% to 50% acetone/hexanes) to provide 6-(4-nitro-lH-pyrazol-l-yl)isoquinoline (374 mg, 86% yield) as a white solid.
