Aim To report a method for synthesis of poly-α,β-( 2-hydroxyethyl)-DL-asparamid-metaxalone (PHEA-Met) prodrug. Methods The prodrug was synthesized by two steps: (1) the intermediate N-Acetyl chlo-ride metaxalonethe is prepared by linking the choroacetic chloride to the metaxalone; (2) The target compound PHEA-Met was synthesized from PHEA and intermediate. It was characterized by IR and DSC. Results The contents of metaxalone in prodrug was more than 16. 1%. Conclusion The method of preparation of the prodrug is simple and usable with mild condition, which has wide application prospect.
