Procedure

A mixture of tert-butyl 2-(2-(2-methylpyridin-4-yl)pyrimidin-5-yl)acetate 183-4 (35 mg, 0.12 mmol) and TFA (0.5 mL) in DCM (3 mL) was stirred at room temperature for 2 hours. The solvents were evaporated to dryness under high vacuum. The crude product, 2-(2-(2-methylpyridin-4-yl)pyrimidin-5-yl)acetic acid 183-5, was dissolved in DMF (2 mL). 1-(4-(6-aminopyridin-3-yl)piperazin-1-yl)ethanone (35 mg, 0.16 mmol) and DIEA (107 uL, 0.61 mmol) were added to the solution before O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluroniumhexafluorophosphate (70 mg, 0.18 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-(2-(2-methylpyridin-4-yl)pyrimidin-5-yl)acetamide 183.
