Participants

Reaction Steps

3-(4-hydroxyphenyl)-1-(4-piperonylpiperazin-1-yl)propan-1-one (0.38 g, 1.0 mmol) was dissolved in DMF (6 mL). To the resulting solution was added 60% sodium hydride (0.05 g, 1.2 mmol) and 2-chloro-4-methyl-5-nitropyridine (0.196 g, 1.1 mmol), and the resulting reaction solution was stirred overnight at room temperature. To the reaction solution was added saturated aqueous ammonium chloride, and extracted with ethyl acetate. The ethyl acetate layer was washed with water and brine. The ethyl acetate layer was dried over anhydrous magnesium sulfate, evaporated, and the residue was purified by silica gel column chromatography (ethyl acetate), to thereby yield the intermediate product 3-(4-(4-methyl-5-nitropyridin-2-yloxy)phenyl)-1-(4-piperonylpiperazin-1-yl)propan-1-one. The 3-(4-(4-methyl-5-nitropyridin-2-yloxy)phenyl)-1-(4-piperonylpiperazin-1-yl)propan-1-one was dissolved in a mixed solvent consisting of ethanol (4 mL) and dioxane (1 mL). To this solution was added 10% palladium-carbon (0.034 g), and the resulting solution was subjected to catalytic reduction for 8 hours at atmospheric pressure and room temperature. The catalyst was removed by filtration, and the filtrate was concentrated under reduced pressure, and the residue was purified by silica gel chromatography (dichloromethane:methanol=20:1), to thereby yield 0.22 g of the title compound.
