该中间体在本合成路线中的序号：(XXXVIII)In an alternative synthesis, the previously reported trichloroethyl ester (XXXVI) was deprotected by treatment with zinc dust in the presence of ammonium acetate yielding acid (XXXVII). This was then coupled to proline trichloroethyl ester (XXXVIII), prepared from N-Boc-L-proline (XXXIII), to furnish amide (XXXIX). Subsequent hydrogenolysis of the O-benzyl group of (XXXIX) provided intermediate (XL)
