Reaction Steps

A solution of compound (X) (3.71 g, 20 mmol), K2CO3 (3.31 g, 24 mmol), 4-benzhydrylpiperazine (XId) (6.06 g, 24 mmol), and KI (3.98 g, 24 mmol) in DMF (20 ml) was stirred at 100° C. for 5 hours, concentrated in vacuo and extracted with dichloromethane. The resulting dichloromethane layer was dried over MgSO4, and subjected to column chromatography on silica gel. The eluate eluted with dichloromethane/ethyl acetate (10/1) was recrystallized from ether to obtain compound (XIId) (5.9 g, yield=61.7% ) as colorless prism-shaped crystals.
