Procedure

To [5-(5-chloro-1H-pyrrolo[2,3-b]pyridine-3-carbonyl)-pyridin-2-yl]-(6-methoxy-pyridin-3-ylmethyl)-carbamic acid tert-butyl ester (587, 0.020 g, 0.040 mmol) in dichloromethane (2.0 mL) was added trifluoroacetic acid (0.30 mL, 0.0039 mol). The reaction was stirred at room temperature for 2 hours, 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 20% to 100% ethyl acetate in hexane to give the desired compound (P-0405, 5.5 mg, 34%). MS (ESI) [M+H+]+=394.3.
