Versuchsvorschrift
9.15 g of methyl 2-[(tert-butoxycarbonyl)amino]-3-[2-(2,6-dichlorophenyl)-6-quinolinyl]propanoate 6 are solubilized in CH2Cl2 (50 ml). TFA (50 ml) is added at 0° C., and the mixture is stirred at RT for 6 h. After evaporation of the solvent, the residue is triturated in diethyl ether and cooled at 5° C. The solid product 33 is obtained by filtration.
