Procedure

91 mg (0.30 mmol) of (2S)-5-tert-butoxy-2-[(tert-butoxycarbonyl)amino]-5-oxopentanoic acid are dissolved in 5 ml of DMF and, after addition of 58 mg (0.3 mmol) of EDCI×HCl and 37 mg (0.30 mmol) of DMAP, stirred at room temperature for 10 minutes. Then 70 mg (0.15 mmol) of 1-butyl-N-(2-hydroxyethyl)-4-[({[4-(trifluoromethoxy)phenyl]amino}-carbonyl)amino]-1H-imidazole-2-carboxamide (Example 81) are added, and the mixture is stirred at room temperature overnight. The reaction mixture is purified by preparative HPLC. The product-containing fractions are evaporated in vacuo.
