In a similar manner to that described in Example 2, ethyl 2-butyl-3-[4-[2-(2′-formylbiphenyl-4-carbonylamino)ethoxy]phenyl]propionate (314 mg), which is the product of Example 46, was reacted with aqueous sodium hydroxide solution (1N, 2.50 ml) and the reaction mixture was treated to afford the crude free acid which was subjected to chromatography on a silica gel thin layer plate using dichloromethane/methanol=10/1 as the eluant to give the title compound (152 mg) as a mass of foam.
