반응 단계

A solution of piperazine (215 mg, 2.5 mmoles), 2-bromo-5-methyl-pyridine (172 mg, 1 mmoles) in dioxane (1 mL) and potassium carbonate (276 mg, 2 mmoles) was irradiated by microwaves for 60 minutes at 180° C. The dioxane was removed under reduced pressure and the residue partitioned between aqueous potassium carbonate and ethyl acetate. The aqueous layer was extracted with ethyl acetate and the combined organic extracts washed twice with water, dried (MgSO4) and filtered. The filtrate was concentrated under reduced pressure and the residue was purified (silica gel, 0-10% methanol in dichloromethane) to provide the title compound as a white solid.
