실험 절차

Synthesized from cyclopropanecarboxylic acid {2-[4-(tert-butyldimethylsilyloxy)phenyl]ethyl}[5-methoxy-2-(6-methoxy-1,2,3,4-tetrahydronaphthalen-2-yl)phenyl]amide (2.3 g) according to an analogous synthetic method to Example 337, to a filtrate of the resulting {2-[4-(tert-butyldimethylsilyloxy)phenyl]ethyl}cyclopropylmethyl[5-methoxy-2-(6-methoxy-1,2,3,4-tetrahydronaphthalen-2-yl)phenyl]amine was added tetrabutylammonium fluoride (1M solution in tetrahydrofuran) (4 ml), and the solution was stirred for 20 minutes at room temperature. The reaction solution was concentrated in vacuo, extracted with ethyl acetate, then sequentially washed with water 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 (1.7 g).
