With potassium acetate;dichloro(1,1'-bis(diphenylphosphanyl)ferrocene)palladium(II)*CH2Cl2; In N,N-dimethyl-formamide; at 100℃;Inert atmosphere; | <strong>[344790-96-1]5-Bromo-4-fluoro-1H-indole</strong> obtained by the method described in Eur. J. Org. Chem. 2956-2969, 2006 (793 mg) was dissolved in N,N-dimethylformamide (30 ml), and bis(pinacolato)diboron (1.88 g), potassium acetate (1.82 g) and a [1,1'-bis(diphenylphosphino)ferrocene]palladium(II) chloride-dichloromethane complex (151 mg) were added. The mixture was stirred with heating under nitrogen atmosphere at 100 C. overnight. The reaction solution was cooled to room temperature and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (developed with ethyl acetate-hexane). The resulting colorless oil was slurry washed with hexane to give the title compound (481 mg) as a colorless solid.MS (EI) m/z: 261M+.1H-NMR (CDCl3) delta: 1.38 (12H, s), 6.65-6.68 (1H, m), 7.14-7.17 (1H, m), 7.18 (1H, s), 7.51 (1H, dd, J=8.3, 5.5 Hz), 8.27 (1H, brs). |

General procedure: The aldehydes were prepared asdescribed previously. Vilsmeier-Haack reagent was generated bythe addition of 2mL of POCl3 over the course of 15 min to 8mL ofdry DMF cooled in an ice-salt bath. After the additionwas complete, the ice bath was removed and the contents of the flask wereallowed to warm to room temperature over approximately 30 min.The substituted indole (21.9 mmol) was dissolved in 10 mL of DMF and added over a period of 15 min to the formylating mixture. Thestirring was continued for 1 h, during which time the flask contentswere heated to 40 C in a hot water bath. A total of 20 mL of 5M NaOH was added, and the mixture was diluted with H2O, quicklybrought to a boil and allowed to cool slowly. The crystals wereremoved by filtration, washed with cold water and vacuum dried.The products obtained were, in most cases, sufficiently pure for thesubsequent reactions. Additionally, the impure aldehydes wererecrystallized from ethanol-water mixtures. The yields varied from48 to 90%. |

With triethylsilane; trichloroacetic acid; In toluene; at 70 - 90℃; for 2.5h; | To a 100 ml round bottom flask were added 2,2,2-trichloroacetic acid (0.246 g, 1.507 mmol), toluene (5 mL) and triethylsilane (0.481 mL, 3.01 mmol). With stirring, the solution was heated to 70 C and a solution of <strong>[344790-96-1]5-bromo-4-fluoro-1H-indole</strong> (0.215 g, 1.005 mmol) and acetone (0.089 mL, 1.205 mmol) in toluene (2.0 mL) was added drop- wise via a pipet. The resulting brown solution was heated at 90 C for 2.5 hours. The solution was cooled to 10 C. The reaction mixture was quenched with 2 M potassium phosphate solution. The mixture was diluted with diethyl ether. The organic layer was separated, dried and concentrated under vacuum to get crude compound. |
