Sodium hydride → HCID 68749054, compound

Participants

Reaction Steps

The title compound was also prepared according to the following method. Specifically, sodium hydride (144 mg, 6 mmol) was added to a solution of 4-nitroindole (973 mg, 6 mmol) in THF and the resulting mixture was stirred for 4 h. 1-(t-butyloxycarbonyl)-4-chloromethyl-7-azaindole (Int-11, 1.5 g, 5.5 mmol) was then added. After the reaction was complete (by TLC), the mixture was quenched with saturated aqueous ammonium chloride. The organic layer was separated and the aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with brine, dried over anhydrous sodium sulfate, filtered, concentrated under reduced pressure, and purified by flash column chromatography to provide 4-[(4-nitro-1H-indol-1-yl)methyl]-1H-pyrrolo[2,3-b]pyridine (254 mg, 16%).
