Procedure

1 mL (12.92 mmol) of trifluoroacetic acid is added to a solution of 0.24 g (0.49 mmol) of 3-[4-(1-tert-butoxycarbonylaminocyclopropyl)phenyl]propynoic acid-(4′-chlorobiphenyl-4-yl)amide in 20 mL dichloromethane and stirred for 24 hours. Then the solvent is eliminated by rotary evaporation and the residue is combined with toluene and again subjected to rotary evaporation. This residue is then triturated with dichloromethane, suction filtered and dried in the air. Yield: 0.22 g (89% of theory); C24H19ClN2O*C2HF3O2 (M=500.90); calc.: molecular ion peak (M+H)+: 387 (Cl); found: molecular ion peak (M+H)+: 387 (Cl); melting point: 160° C.-164° C.
