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) and DBU (0.15 g) were dissolved in acetonitrile (10 ml). Phenyl isocyanate (66 mg) was added thereto, and mixed at room temperature for 2 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 sodium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified with silica gel column (ethyl acetate to ethyl acetate/methanol=5/1) and solidified with ethyl acetate and diethyl ether to obtain the title compound (0.14 g, 59%) as colorless powder.
