Procedure

Trans-2-(4-Chloro-benzenesulfonylamino)-cyclohexanecarboxylic acid (0.095 g, 0.3 mmol) is dissolved in CH3CN. O-1,2-Dihydro-2-oxo-1-pyridyl)-N,N,N′,N′-tetramethyluronium tetrafluoroborate (TPTU, 90.2 mg, 0.3 mmol), N-Ethyldiisopropylamine (DIPEA, 0.208 ml, 1.21 mmol) are added. The amino-(3-hydroxy-phenyl)-acetonitrile in CH3CN (1.5 ml) is added. The mixture is stirred at RT for 16 hours. The solution is filtered and concentrated. The residue is dissolved in CH2Cl2 (15 mL) and extracted with NH4Cl (2×10 ml). The H2O layers are extracted with CH2Cl2 (2×15 ml). The collected CH2Cl2 layers are dried over MgSO4 and evaporated. The solid is purified by preparative HPLC.
