Procedure

To a solution of 2-(7-(5-(ethoxycarbonyl)-1H-pyrazol-3-yl)-4-fluoro-1H-pyrrolo[2,3-c]pyridin-3-yl)-2-oxoacetic acid (0.017g, 0.049 mmol) in DMF (1.5 mL) was added TBTU (0.017 g, 0.054 mmol), diisopropylethylamine (0.15 mL), and 1-(3-phenyl-1H-pyrazol-4-yl)piperazine (0.011 g, 0.049 mmol). The mixture was stirred under N2 at rt for 14.5 h and was quenched with 10 mL of H2O. The solvent was removed under reduced pressure, and the residue was dissolved in DMF. The DMF solution was passed though a plug of celite to remove solids, and the DMF solution was purified by prep HPLC to give the title compound as a white solid (13.3 mg).
