Procedure

2-(3-cyano-4-(2-fluoropyridin-4-yl)phenyl)acetic acid 206-6 (50 mg, 0.20 mmol) was dissolved in DMF (2 mL). 1-(4-(6-aminopyridin-3-yl)piperazin-1-yl)ethanone (52 mg, 0.23 mmol) and DIEA (170 uL, 0.98 mmol) were added to the solution before O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluroniumhexafluorophosphate (111 mg, 0.29 mmol). The mixture was stirred at room temperature overnight. The solvent was removed by rotary evaporation. The crude product was purified by reverse phase HPLC to give N-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-2-(3-cyano-4-(2-fluoropyridin-4-yl)phenyl)acetamide 211.
