実験手順

To a mixture of the compound obtained in Example 22 (2) (1.2 g) and N,N-dimethylformamide (23 ml), 60% sodium hydride (204 mg) was added at 0° C. and the mixture was stirred at the same temperature for 20 minutes. To the reaction mixture was added 4-fluorobenzyl bromide (0.65 ml) at 0° C. and the mixture was stirred at 15 to 30° C. for 2 hours. 2N hydrochloric acid was added thereto, and the mixture was extracted with ethyl acetate. The organic layer was washed with water, dried over sodium sulfate and concentrated under reduced pressure. The resulting residue was subjected to silica gel column chromatography (dichloromethane) to obtain 1 g of the desired product in a white amorphous form.
