DHQHS 2 Use and Manufacturing

Methods of Manufacturing

LiBHEtSodium borohydride (2.02 g, 53.19 mmol) was added in five portions within 30 minutes to the solution of artemisinin (5 g, 17.73 mmol) in methanol (60 mL) under 5. The reaction mixture was kept stirring for approximately 1h at 0–5, the acetic acid was added to adjust PH =7.0. The reaction solution was concentrated to remove most of methanol, diluted with cold water (60 mL) and stirred for 15 min at room temperature. The precipitate was collected, washed with water (20 mL*3) and dried to afford product as white solid, 4.51 g, yield: 89.57percent.Dihydroartemisinin (DHA) synthesis:Artemisinin (5.0 g, 18 mmol) was dissolved in anhydrous methanol (120 mL).It was placed in an ice water bath, and NaBH4 (1.0 g, 27 mmol) was added portionwise with stirring, and was added over 20 min. The reaction is about 2 hours, and the reaction is completed.Adjust pH 6-7 with glacial acetic acid and distill off most of the methanol.Stir with water for 15 min, filter and collect the precipitate.Wash three times with water, dry, Obtained as a white solid (3.0 g, 59percent).

Uses
