Procedure

To a solution of the compound obtained in Example 6 (3) (3.0 mg) in N,N-dimethylformamide (0.5 ml), 60% sodium hydride (0.7 mg) was added at 0° C. under nitrogen atmosphere and the mixture was stirred at the same temperature for 15 minutes. 4-Fluorobenzyl bromide (3.1 mg) was then added thereto at 0° C. and the mixture was stirred at 15 to 30° C. for 1 hour. After completion of the reaction, the reaction solution was poured into a saturated aqueous sodium hydrogencarbonate solution and extracted with toluene. The organic layer was washed with a saturated aqueous NaCl solution, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The resulting residue was separated using silica gel preparative thin-layer chromatography (methanol:chloroform=1:20) to obtain 2.4 mg of the desired product as a white crystal.
