Procedure

1-Amino-cyclohexanecarboxylic acid cyanomethyl-amide (0.6 mmol), 4-(4-isopropyl-piperazin-1-yl)-benzoic acid hydrochloride (0.6 mmol), HOBT (0.6 mmol), WSCD (0.6 mmol) and triethylamine (0.6 mmol) are dissolved in DMF (2 ml) and stirred overnight at rt. After evaporation of the solvent, the residue is dissolved in a mixture of water and sodium carbonate (to ensure slightly basic conditions) and extracted three times with ethyl acetate. The combined extract is dried over sodium sulfate and evaporated. The residue is suspended in ethyl acetate/diethylether and the solid filtered of and dried (vacuum). A white powder with mp. 218-220° C., Rf=0.28 (CH2Cl2/MeOH=9:1) is obtained.
