実験手順: To a solution of 2-isopropyl-1H-indole-3-carbaldehyde (Compound 39, 1.19 g, 6.4 mmol) in DMF (6.0 ml) was added benzyl bromide (1.5 ml, 12.8 mmol) and K2CO3 (2.65 g, 19.2 mmol). The mixture was stirred at room temperature for 24 h and was diluted with EtOAc, washed with H2O, brine, dried over Na2SO4, and concentrated in vacuo. The residue was purified by flash chromatography on silica gel eluting with 0-30% EtOAc-hexanes to yield 1-benzyl-2-isopropyl-1H-indole-3-carbaldehyde (Compound 40) as a light brown solid. washed with H2O, brine dried over Na2SO4 concentrated in vacuo The residue was purified by flash chromatography on silica gel eluting with 0-30% EtOAc-hexanes

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 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. The reaction was stirred for 1 h while it washed with aq. NaHCO3, brine dried over Na2SO4 concentrated in vacuo The residual solid was washed with Et2O
