Trifluoroacetic acid → 5-(1H-pyrrolo(2,3-b)pyridin-3-ylmethyl)-N-((4-(trifluoromethyl)phenyl)methyl)pyridin-2-amine

Participants

Reaction Steps

Into a round bottom flask was added compound 14 (200.0 mg, 0.50 mmol) and trifluoroacetic acid (5.0 mL, 0.065 mol) and triethylsilane (3.0 mL, 0.019 mol). The reaction was stirred at room temperature for 30 min, poured into aqueous sodium bicarbonate, and the product was extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, concentrated and purified to give pure product 12 (Table 1 Cmpd 1-3) (120.0 mg, yield=62.8%) as a white solid (M+1=383).
