Preparation method for phosphamide compound used for synthesis chiral drug
-
Paragraph 0032-0034, (2020/05/29)
The invention provides a preparation method for a phosphamide compound used for synthesis of a chiral drug. According to the invention, a compound II with high yield and high purity can be prepared byadopting a NaHCO3 aqueous solution with a specific pH value and a specific volume-to-mass ratio as a solvent for pulping and controlling a temperature and a stirring speed during pulping. By adoptionof a reaction system provided by the invention, an organic solvent is not needed; the discharge of a large amount of an organic solvent waste liquid is reduced; and the process is environmentally-friendly, green and pollution-free.
