Water → 6-Bromoindole-3-carbaldehyde

Participants

Reaction Steps

POCl3 (980 mg, 6.4 mmol) was added dropwise to DMF (3 mL) cooled in an ice bath. The mixture was stirred at 0° C. for 30 min before a solution of 6-bromo-1H-indole (1.0 g, 5.1 mmol) in DMF (7 mL) was slowly added at 0° C. The mixture was stirred at room temperature for 3 h before being poured into water and neutralized with 1N NaOH. The crude product was collected by filtration and used in next step without further purification. LCMS (m/z): 224.1 [M+H]+.
