A solution of 6-chloro-1-(6-fluoro-2-pyridyl)pyrazolo[4,3-c]pyridine (100 mg, 0.40 mmol) and 1-N-Boc-piperazine (380 mg, 2.0 mmol) in dimethyl sulfoxide (3.0 mL) was heated at 95° C. 4 h. The reaction was quenched with water and extracted with EtOAc. The organic layers was dried with sodium sulfate, filtered, and concentrated in vacuum. The crude product was purified by flash chromatography (EtOAc/Heptane 25% EtOAc) to give the desired product 110 mg 66% yield. MS (ESI) m/z: 415.1 [M+H]+
