Procedure

To a solution of the compound obtained in Example 5 (4) (2.3 mg) in N,N-dimethylformamide (0.5 ml), 60% sodium hydride. (0.5 mg) was added at 0° C. and the mixture was stirred at the same temperature for 15 minutes. p-Fluorobenzyl bromide. (2.4 mg) was then added thereto at 0° C. and the mixture was stirred at 15 to 30° C. for 1 hour. The reaction solution was poured into a saturated aqueous sodium hydrogencarbonate solution, extracted with toluene, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The resulting residue was separated using silica gel preparative thin-layer chromatography (chloroform:methanol=100:1) to obtain 1.7 mg of the desired product as a white powder.
