Versuchsvorschrift

Compound 184 (100 mg, 0.29 mmol) obtained in Reference Example 181 was dissolved in 2 ml of dimethylformamide. To the solution were added 162 mg (1.17 mmol) of potassium carbonate and 0.28 ml (2.35 mmol) of benzyl bromide, and the mixture was stirred at 80° C. for 2.5 hours. Water was added thereto under ice cooling to dissolve potassium carbonate and the deposited crystals were collected by filtration. The collected crude crystals were dissolved in chloroform, washed with a saturated aqueous solution of sodium chloride and dried over anhydrous sodium sulfate, followed by evaporation under reduced pressure. The residue was recrystallized from hexane/ethyl acetate to give 67 mg (yield 53%) of Compound 185 as yellow needles.
