Reaction Steps

To [5-(5-chloro-1H-pyrrolo[2,3-b]pyridine-3-carbonyl)-pyridin-2-yl]-(2-fluoro-benzyl)-carbamic acid tert-butyl ester (584, 0.030 g, 0.062 mmol) in dichloromethane (1.0 mL) was added trifluoroacetic acid (1.0 mL, 0.013 mol). The reaction was stirred at room temperature overnight, then poured into aqueous potassium carbonate, and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 2% to 15% methanol in dichloromethane to give the desired compound (P-0404, 2.8 mg, 12%). MS (ESI) [M+H+]+=381.0.
