0.60 g(2.5 mmol) of 5-methyl-5-naphthalen-1-yl-imidazolidin-2,4-dione prepared in Preparation 1, 1.02 g(2.76 mmol) of 3-(1-triphenylmethyl-imidazol-4-yl)-propanol and 0.87 g(3.3 mmol) of triphenylphosphine (Ph3P) were dissolved in 50 ml of tetrahydrofuran. 0.52 ml(3.3 mmol) of diethylazodicarboxylate[DEAD] was added thereto and the resulting solution was stirred for 24 hours. Tetrahydrofuran was removed under reduced pressure and the residue was subjected to chromatography using ethyl acetate the eluent to obtain 1.17 g(Yield: 80%) of the title compound.
