Reaction Steps

To 3-[6-(4-chloro-benzylamino)-pyridazin-3-ylmethyl]-pyrrolo[2,3-b]pyridine-1-carboxylic acid tert-butyl ester (523, 50.0 mg, 0.111 mmol) in dichloromethane (10.0 mL) was added trifluoroacetic acid (0.30 mL, 0.0039 mol). The reaction was stirred at room temperature overnight. The reaction was concentrated, 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 washed with ethyl acetate and hexane to give an off-white solid (P-0092, 7.3 mg, 19.0%). MS (ESI) [M+H+]+=350.1.
