0.082 g(0.14 mmol) of 3-[3-(1-triphenylmethyl-imidazol-4-yl)-propyl]-5-methyl-5-naphthalen-1-yl-imidazolidin-2,4-dione prepared in Example 1-1) and 0.023 ml(0.21 mmol) of ethyl bromoacetate were dissolved in 5 ml of dimethylformamide. 0.017 g(0.21 mmol) of sodium hydride [NaH] was added thereto and the resulting solution was stirred for one hour. Dimethylformamide was removed under reduced pressure and the residue was dissolved in ethyl acetate and then washed with saturated sodium chloride solution. Removal of ethyl acetate under reduced pressure provided 0.092 g(Yield: 99%) of title compound.
