Versuchsvorschrift

2-(1-(2-Amino-2-phenylacetyl)-4-piperidinyl)-5-methyl-1,2-dihydro-3H-imidazo[1,5-c]imidazol-3-one dihydrochloride (0.21 g) obtained in Example 115a) was dissolved in acetonitrile (5.0 ml). Triethylamine (0.14 ml) and 4-chloro-2-methylphenyl isocyanate (80 mg) were added thereto, and mixed at room temperature for 15 hours. The solvent was distilled off under reduced pressure, and the residue was dissolved in ethyl acetate. The reaction mixture was washed with an aqueous sodium hydrogen carbonate solution and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified with basic silica gel column (ethyl acetate/hexane=1/1 to ethyl acetate). The product was crystallized from ethyl acetate-diethyl ether to obtain the title compound as colorless powder (0.16 g, 61%).
