Procedure

In a similar manner to that described in Example 5, a reaction was carried out using ethyl 3-[4-(2-aminoethoxy)phenyl]-2-butylpropionate (880 mg), which is the product of Reference example 6, 4′-methoxymethoxy-3′,5′-dimethylbiphenyl-4-carboxylic acid (859 mg), which is the product of reference example 17(b), and carbonyldiimidazole (577 mg) and the reaction mixture was treated to afford the desired compound (1 18 g) as colorless crystals.
