실험 절차

Reaction of 3-hydroxyproline methyl ester with DIAD, triphenylphosphine and diphenylphosphoryl azide provides the desired 3-azido proline methyl ester. Transformation is typically carried out at low temperatures, e.g., 0° C., and after the addition, the reaction is allowed to warm to ambient temperature, e.g., about 25° C.
