Using an analogous procedure to that described in the second paragraph of the portion of Example 1 which is concerned with the preparation of starting materials, 1-ethoxycarbonyl-3-hydroxy-3-(2-methylthiothien-4-yl)pyrrolidine was reacted with methyl iodide to give 1-ethoxycarbonyl-3-methoxy-3-(2-methylthiothien-4-yl)pyrrolidine as an oil in 75% yield.
