Dimethylformamide → 5-Bromo-1-(triisopropylsilyl)-1H-pyrrolo[2,3-b]pyridine

Participants

Reaction Steps

Into a Round bottom flask was added 5-bromo-7-azaindole 1 (900.0 mg, 0.004568 mol) and N,N-Dimethylformamide (25.0 mL, 0.323 mol) and Sodium hydride (0.20 g, 0.0050 mol) at room temperature. After 10 minutes, Triisopropylsilyl chloride (1.1 mL, 0.0050 mol) was added to the reaction mixture. The reaction mixture was stirred at room temperature overnight. The reaction mixture was poured into water, extracted with EtOAc. The organic layer was washed with brine, dried over sodium sulfate, concentrated and purified with biotage to give product 20 (1.2 g).
