Versuchsvorschrift

Synthesized from 4-{2-[5-methoxy-2-(6-methoxy-1,2,3,4-tetrahydronaphthalen-2-yl)phenylamino]ethyl}phenol according to an analogous synthetic method to Example 201, to a solution of the resulting {2-[4-(tert-butyldimethylsilyloxy)phenyl]ethyl}[5-methoxy-2-(6-methoxy-1,2,3,4-tetrahydronaphthalen-2-yl)phenyl]amine (2.3 g) in tetrahydrofuran (50 ml) was added triethylamine (895 mg), cyclopropanecarbonyl chloride (693 mg) was added dropwise thereto on an ice bath followed by stirring for 30 minutes at room temperature. The solution was extracted with ethyl acetate, then sequentially washed with a saturated aqueous solution of sodium bicarbonate and brine, dried over anhydrous magnesium sulfate, and then the solvent was evaporated in vacuo. The residue was purified by silica gel column chromatography (hexane-ethyl acetate system) to provide the title compound (2.3 g).
