Procedure

To a solution of 3,4-dichloro-N-[6-(4-piperazin-1-ylmethylphenoxy)pyridin-3-yl]benzamide (300 mg, 0.66 mmol) in DMF (10 mL) were added piperonylic acid (120 mg, 0.72 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (140 mg, 0.73 mmol) and 1-hydroxybenzotriazole monohydrate (100 mg, 0.74 mmol) under ice cooling. The resulting reaction solution was stirred overnight at room temperature. To the residue was added a saturated sodium bicarbonate solution, and extracted with ethyl acetate. The ethyl acetate layer was washed with a saturated sodium bicarbonate solution and brine. The ethyl acetate layer was dried over anhydrous magnesium sulfate, and evaporated, to thereby yield 110 mg of the title compound.
