Daunorubicin (D194500) impurity. Daunomycin analog antitumor. | [Preparation]
9.0 g of the raw material was suspended in 460 mL of purified water. Then the temperature was cooled to 0 ~ 5 °C, and 60 mL of 3.5% sodium hydroxide solution was added dropwise for 50 minutes. After the reaction was complete, the pH was adjusted to 5.0 with hydrochloric acid. The reaction solution was subsequently washed twice with 200 mL of dichloromethane and the aqueous phase was collected. 1200 mL of dichloromethane and 80 mL of methanol were added to the aqueous phase, and the pH was adjusted to 8.2 with a 0.1 mol/L sodium hydroxide solution. Collect the organic phase. The organic phase was concentrated to dryness under reduced pressure Daunorubicin7.48g.
