该中间体在本合成路线中的序号:(VI)

Optically active sulpiride is prepared by converting levo-proline (I) to the correspondig levorotatory acetylproline (II), followed by reduction, chlorination and amination to afford levorotatory N-ethyl-2-aminomethylpyrrolidine (V), which, upon treatment with an ester of 2-methoxy-5-sulfamoylbenzoic acid (VI), yields N-(1-ethyl-2-pyrrolidinomethyl)-2-methoxy-5-sulfamoylbenzamide, that is, the levorotatory enantiomer of sulpiride.
