该中间体在本合成路线中的序号:(III)The esterification of (3aR,7aS)-octahydroindole-2(S)-carboxylic acid (I) with benzyl alcohol (II) by means of SOCl2 gives the corresponding benzyl ester (III), which is condensed with N-[1(S)-(ethoxycarbonyl)-3-phenylpropyl]-(S)-alanine (IV) by means of 1-hydroxybenzotriazole, N-ethylmorpholine and dicyclohexylcarbodiimide (DCC) in DMF giving the benzyl ester (V) of the desired product. Finally, this compound is debenzylated by hydrogenation with H2 over Pd/C in ethanol.
