Procedure

To a solution of 40 mg of (S)-3-hydroxytetrahydrofuran in tetrahydrofuran was added 15 mg of 60% sodium hydride (oily) in an atmosphere of nitrogen gas, and the mixture was stirred at room temperature for 15 minute. To the reaction mixture were added 150 mg of 5-(chloromethyl)-3-(3-fluorophenyl)-1-trityl-1H-indazole produced in Production Example I-32 and 45 mg of sodium iodide, followed by stirring at room temperature for five days. After adding water to the reaction mixture, it was extracted with 20 ml of ethyl acetate. The organic layer was sequentially washed with half-saturated aqueous sodium chloride solution and brine, dried over anhydrous magnesium sulfate and the solvent was evaporated. The resulting crude product was purified and separated by silica gel column chromatography (ethyl acetate:toluene=0:1 to 1:9), to give 84 mg of the title compound as a white amorphous powder.
