Procedure

212 mg (5.3 mmol, 10 eq) of sodium hydroxide are added to a solution of 220 mg (0.53 mmol, 1 eq) of methyl 3-(5-{3-[(methyloctanoylamino)methyl]phenyl}thiophen-2-yl)acrylate in 4 ml of 9/1 tetrahydrofuran/methanol. The reaction mixture is stirred for two hours at room temperature. The reaction is stopped by adding 20 ml of water and 3 ml of acetic acid and is 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 (90/10 dichloromethane/methanol). The oil obtained is crystallized from pentane. 155 mg of 3-(5-{3-[(methyloctanoylamino)methyl]phenyl}thiophen-2-yl)acrylic acid are obtained. Yield=73%. m.p.=102-104° C.
