Colorless crystals of 1-[1-(1,2,3,4-tetrahydronaphthalen-2-ylacetyl)-L-prolyl]pyrrolidine were prepared in the same manner as in Example 1, except that 1-(1,2,3,4-tetrahydronaphthalen-2-ylacetyl)-L-proline and pyrrolidine were used instead of 3-(2-indanylacetyl]-L-thioproline and thiazolidine, respectively (yield: 46%).
