Versuchsvorschrift

In a similar manner to that described in Example 5, a reaction was carried out using ethyl 3-[4-(2-aminoethoxy)phenyl]-2-butylpropionate (375 mg), which is the product of Reference example 6, 4′-methoxycarbonylbiphenyl-4-carboxylic acid (328 mg) and carbonyldiimidazole (225 mg) and the reaction mixture was treated to afford the title compound (257 mg) as colorless crystals.
