In a similar manner to that described in Preparative Example 1(iii)′ above, a reaction was performed, using (2S)-1-benzyloxycarbonyl-2-(3-ethoxycarbonyl-2-oxopropyl)-4-methylpyrrolidine [obtained as described in Preparative Example 8(v)′ above] instead of (2S,4R)-1-benzyloxycarbonyl-2-(3-ethoxycarbonyl-2-oxopropyl)-4-methoxypyrrolidine, to give the title compound as a colorless oil (yield: 34%).
