Reaction Steps

The above carbamic acid phenyl ester (1.0 g, 2.9 mmol) was mixed with 3-{4-[(4-tert-butyl-cyclohexylamino)methyl]benzoylamino}propionic acid methyl ester, trifluoroacetate (1.07 g, 2.9 mmol), prepared as described above and triethylamine (1.2 mL, 8.6 mmol) in dichloromethane (55 mL) and the resulting mixture was refluxed for 4 hours. The cooled reaction mixture was diluted with toluene (50 mL) and washed with water (3×50 mL) and a mixture of water and saturated aqueous sodium chloride (1:1, 3×100 mL), dried (MgSO4) and concentrated in vacuo to afford 1.2 g (67%) of 3-{4-[3-(3,5-bis-trifluoromethylphenyl)-1-(4-tert-butyl-cyclohexyl)ureidomethyl]benzoylamino}propionic acid methyl ester as a solid.
