Versuchsvorschrift

200 mg (5 mmol, 10 eq) of sodium hydroxide are added to a solution of 221 mg (0.51 mmol, 1 eq) of methyl 3-(3′-{3-[2-(4-fluorophenyl)ethyl]-1-methylureido}biphenyl-4-yl)propanoate in 6 ml of an 8/2 tetrahydrofuran/methanol mixture. The reaction mixture is stirred for 3 hours at room temperature. The reaction is stopped by addition of 10 mL of water and 2 mL of acetic acid and then extracted with ethyl acetate. The organic phases are combined and dried over sodium sulfate. The solvents are evaporated off and the residue is then chromatographed on silica gel (70/30 heptane/ethyl acetate). 180 mg of 3-(3′-{3-[2-(4-fluorophenyl)ethyl]-1-methylureido}biphenyl-4-yl)propanoic acid are obtained (m.p.=146° C.). Yield=84%
