Reaction Steps

193 mg of methyl 3-({3,5-dichloro-4-[(3-isopropyl-1H-indol-5-yl)oxy]phenyl}-amino)-3-oxopropanoate (Example 7) are stirred in 3 ml of ethanol with 1 ml of 1N NaOH for one hour at room temperature. The solvent is removed in vacuo and the residue is taken up in dichloromethane. The mixture is shaken with water, the organic phase is dried and the solvent is removed in vacuo. By stirring with diethyl ether, 143 mg of 3-({3,5-dichloro-4-[(3-isopropyl-1H-indol-5-yl)oxy]phenyl}amino)-3-oxopropionic acid are obtained.
