実験手順

In a similar manner to that described in Example 5, a reaction was carried out using ethyl 3-[4-(2-aminoethoxy)phenyl]-2-butylpropionate (358 mg), which is the product of Reference example 6, 3′-methoxymethoxymethylbiphenyl-4-carboxylic acid (333 mg), which is the product of reference example 15(c), and carbonyldiimidazole (238 mg) and the reaction mixture was treated to afford the desired compound (573 mg) as a brown syrup.
