Procedure
128 mg of 1-(4-Fluorophenyl)-5-(pyridin-4-yl)-4-imidazolin-2-one (the compound of Example 1), 61 μl of cyclopentylmethanol, 197 mg of triphenylphosphine and 295 μl of diethyl azodicarboxylate were dissolved in 2.5 ml of methylene chloride, and the mixture was stirred at room temperature for 24 hours. The reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (chloroform: ethyl acetate=19:1). The obtained compound was treated with hydrochloric acid, to give 75 mg of the title compound as powder.
