Procedure

(1R,2R)-2-(4-{[Acetyl(2-pyridinyl)amino]methyl}phenyl)cyclohexanecarboxylic acid (0.44 g) is suspended in DMF (15 ml), (2S)-2-amino-2-phenylethanamide (0.37 g), triethylamine (0.68 ml), 1-hydroxybenzotriazole (0.18 g) and EDC hydrochloride (0.27 g) are admixed and the mixture is stirred at room temperature for 2 days. The suspension is diluted with water and extracted with dichloromethane and the organic phases are washed with saturated sodium chloride solution, dried over sodium sulphate and concentrated. Chromatography (silica gel, dichloromethane:methanol:saturated aqueous ammonia solution=50:1:0.05 to 20:1:0.05 gives (1R,2R)-2-(4-{[acetyl(2-pyridinyl)amino]methyl}phenyl)-N-[(1S)-2-amino-2-oxo-1-phenylethyl]cyclohexanecarboxamide (0.39 g) as a colourless solid.
