Versuchsvorschrift
To a solution of 2-(N′-(4-chlorophenyl)ureido)-3-phenylpropanoic acid (0.16 g) obtained in Example 1b) and HOBt (0.12 g) in DMF (10 ml) was added WSC (0.14 g), and the reaction mixture was mixed at room temperature for 15 minutes. Then, 5-methyl-2-(4-piperidinyl)-1,2-dihydro-3H-imidazo[1,5-c]imidazol-3-one (0.11 g) obtained in Reference Example 1 and N-methylmorpholine (0.08 ml) were added thereto. The reaction mixture was mixed at room temperature for 15 hours, and then the solvent was distilled off under reduced pressure. The residue was dissolved in ethyl acetate, 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=10/1). The product was washed with diethyl ether to obtain the title compound as colorless powder (0.13 g, 50%).
