Participants

Reaction Steps

POCl3 (0.86 ml, 9.4 mmol) was added dropwise to anhydrous DMF (4 ml) at 0° C. with stirring. After 30 min, this solution was added dropwise to a solution of 2-isopropyl-1H-indole (Compound 38, 1.24 g, 7.8 mmol) in DMF (16 ml) at 0° C. under argon. The reaction was stirred for 1 h while it warmed up to room temperature. The reaction was diluted with EtOAc, washed with aq. NaHCO3, brine, dried over Na2SO4, and concentrated in vacuo. The residual solid was washed with Et2O to yield 2-isopropyl-1H-indole-3-carbaldehyde (Compound 39) as a beige solid.
