Versuchsvorschrift

To 2-(3-{3-[(2-Chloro-3-trifluoromethyl-benzyl)-diphenylethyl-amino]-propoxy}-phenyl)-malonic acid monomethyl ester (22 mg, 0.03 mmol) in diethyl ether (1 ml) was added lithium aluminum hydride (100 uL) at 0° C. The reaction was allowed to warm to room temperature before the addition of brine and ethyl acetate. The combined organic layers were dried over magnesium sulfate and evaporated. The crude product was purified by HPLC (YMC CombiPrep ODS-A, 50×20 mm, 20 mL/min, A: acetonitrile B: water, A: 60 to 100% during 10 min, UV detection at 254 nm) to give the title compound free amine as an oil. MS m/e 598.2(M+H)+. To a solution of the free amine in diethyl ether was added HCl in diethyl ether (1.0M). The suspension was evaporated and dried to give the title compound as a white solid (2 mg, 10%).
