Procedure

To a solution of the compound obtained in Example 11 (3) (20 mg) in N,N-dimethylformamide (2 ml), 60% sodium hydride (4.4 mg) was added at 0° C. under nitrogen atmosphere and the mixture was stirred for 30 minutes, followed by addition of 4-fluorobenzyl bromide (26 mg), and the reaction mixture was stirred for further 30 minutes. The reaction solution was then poured into a saturated aqueous sodium hydrogencarbonate solution and extracted with toluene. The organic layer was washed with water and a saturated aqueous NaCl solution, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The resulting residue was separated using silica gel preparative thin-layer chromatography (hexane:ethyl acetate=1:1) to obtain 18 mg of the desired product as a yellow powder.
