실험 절차

To a solution of pivalic acid 6-(2-ethylamino-4-methoxyphenyl)-5,6,7,8-tetrahydronaphthalen-2-yl ester (65 mg) and 4-(8-methyl-8-azabicyclo[3.2.1]oct-3-yloxy)benzaldehyde (65 mg) in 1,2-dichloroethane (2 ml) were sequentially added acetic acid (0.07 ml) and sodium triacetoxyborohydride (120 mg) under a nitrogen atmosphere, and the solution was stirred overnight at room temperature. Tetrahydrofuran and aqueous ammonia were sequentially added thereto followed by stirring, the solution was 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 NH silica gel column chromatography (hexane-ethyl acetate system) to provide the title compound (58 mg).
