実験手順

In a similar manner to that described in Preparative Example 1(iii)′ above, a reaction was conducted, using (2S,4R)-1-benzyloxycarbonyl-2-(3-ethoxycarbonyl-2-oxopropyl)-4-phenylpyrrolidine [obtained as described in Preparative Example 6(iv)′ above] instead of (2S,4R)-1-benzyloxycarbonyl-2-(3-ethoxycarbonyl-2-oxopropyl)-4-methoxypyrrolidine, to give the title compound as a pale yellow oil (yield: 27%).
