Reaction Steps

2,6-dimethylpiperazine (291 mg, 2.55 mmol) and 2,3-dichloropyridine (377.4 mg, 2.55 mmol) were charged to a microwave vial, dissolved in DMF (0.25 mL) and added with diisopropylethylamine (1.11 mL, 6.38 mmol). The reaction mixture was irradiated at 165° C. for 30 minutes. The reaction was complete as determined by TLC. After solvent removal the crud product was purified via flush column chromatography to afford 1-(3-chloropyridin-2-yl)-3,5-dimethylpiperazine in 64.4% yield (370 mg).
