Reaction Conditions

Reaction Steps

To a solution of the compound of Example 34 (500 mg) in DMF (10 mL), potassium carbonate (500 mg) and m-chlorobenzyl bromide (0.16 mL) were added and the mixture was stirred at 70° C. for 1 hour. The reaction mixture was then poured into water and was extracted with ethyl acetate. The organic phase was sequentially washed with water and a saturated aqueous solution of sodium chloride and was dried with anhydrous sodium sulfate. The solvent was removed by distillation under reduced pressure and the residue was purified by silica gel column chromatography (hexane:ethyl acetate=3:1) to obtain the desired product (520 mg) as a colorless powder.
