Versuchsvorschrift

A solution of compound (VIII) (9.28 g, 50 mmol), N,N-dimethylaminoethylchloride hydrochloride (XIe) (7.92 g, 55 mmol), and K2CO3 (16.58 g, 120 mmol) in acetone (93 ml) was refluxed for 20 hours with stirring. After the reaction was complete, the reaction mixture was concentrated in vacuo. The residue was extracted with ethyl acetate. The layer of ethyl acetate was dried over MgSO4 and subjected to column chromatography on silica gel. From the eluate eluted with ethyl acetate, compound (XIIe) (3.3 g, yield=64.3%) was obtained as an oil.
