In a manner similar to that of Example (19g), by reaction of 200 mg (5.0 mmol, 4.8 eq) of sodium hydroxide and 490 mg (1.03 mmol, 1 eq) of ethyl 3-{3′-[3-(4-butoxyphenyl)-1-methylureido]biphenyl-4-yl}propanoate in 6 ml of a tetrahydrofuran/methanol mixture (8/2), and after recrystallization from ethyl acetate/heptane, 330 mg of 3-{3′-[3-(4-butoxyphenyl)-1-methylureido]biphenyl-4-yl}propanoic acid are obtained in the form of white crystals. (m.p.=165° C.). Yield=71%
