1-Piperonylpiperazine → HCID 68522097, compound

Participants

Reaction Steps

To a solution of {methyl[3-methyl-4-(5-nitropyridin-2-yloxy)phenyl]amino}acetic acid (0.93 g, 2.9 mmol) in DMF (40 mL) were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.67 g, 3.5 mmol), 1-hydroxybenzotriazole monohydrate (0.54 g, 3.5 mmol), and 1-piperonylpiperazine (0.68 g, 3.08 mmol). The reaction mixture was stirred for 15 hours at room temperature under a nitrogen atmosphere. To the resulting solution was added water and extracted with ethyl acetate. The ethyl acetate layer was washed with water and then dried over anhydrous magnesium sulfate. The solvent was evaporated, and the residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=2:1→dichloromethane:methanol=100:1), to thereby yield 1.2 g of the title compound.
