Butyl acrylate (36 mL, 0.25 mol) was mixed with 300 mL of methanol, and then the mixture was slowly added to the second solution to form a third solution. The third solution was stirred at room temperature for 3 hours. The reaction product was extracted by diethyl ether, and was then distilled under reduced pressure to obtain yellow liquid butyl 4,4-dinitropentanoate (21.5 g, yield: 87%).
