Isopropyl iodide → 5-Bromo-1-(1-methylethyl)-1H-indole-3-carboxaldehyde

Participants

Reaction Steps

Cesium carbonate (545 mg, 1.67 mmol) was added to a stirred room temperature of 5-bromo-1H-indole-3-carbaldehyde (125 mg, 0.56 mmol) in DMF (1.0 mL) and the mixture was stirred at room temperature for 15 minutes. Then 2-iodopropane (0.112 mL, 1.116 mmol) was added and the solution was stirred at 80° C. for 2 hours. The solvent was removed under reduced pressure and the residue was partitioned between ethyl acetate (2×20 mL) and saturated sodium bicarbonate (5 mL), washed with brine (10 mL), dried over sodium sulfate, filtered and concentrated under reduced pressure to give the title compound (148 mg).
