実験手順
Using an analogous procedure to that described in the fourth paragraph of the portion of Example 28 which is concerned with the preparation of starting materials, 5-fluoro-3-[4-(2-methyl-1,3-dioxolan-2-yl)phenylthio]bromobenzene was reacted with 1-ethoxycarbonylpyrrolidin-3-one to give 1-ethoxycarbonyl-3-{5-fluoro-3-[4-(2-methyl1,3-dioxolan-2-yl)phenylthio]phenyl}-3-hydroxypyrrolidine as a gum in 50% yield.
