399-51-9, 6-Fluoro-1H-indole is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: Oxalyl chloride (0.3 mL) was added in a drop-wise manner to cooled (ice-bath) DMF (3 mL) under stirring. The mixture was then stirred at 0 C for 1 h. A solution of the substituted indole (4 mmol) in DMF (1.5 mL) was then added to the reaction mixture in a dropwise manner. The resulting mixture was stirred at room temperature for 5 h. A 2 N solution of sodium hydroxide (2 mL) was then added, and the mixture was heated at 100 C for 10 min. The mixture was then cooled and extracted with ethyl acetate (3 X 50 mL). The organic layers were combined and washed with sequentially water and brine. The organics were dried (Na2SO4) and distilled to dryness to give the crude residue, which was purified by flash column chromatography using ethyl acetate/petroleum ether (3:1, v/v) as the eluent to give pure indole-3-carbaldehyde (4a-k).
399-51-9, As the paragraph descriping shows that 399-51-9 is playing an increasingly important role.
