Participants

Reaction Steps

To a solution of 6-{2-[2-(4-hydroxyphenyl)ethylamino]benzyl}-5,6,7,8-tetrahydronaphthalen-2-ol (1.0 g) in tetrahydrofuran (15 ml) were sequentially added acetic acid (in catalytic amounts), sodium triacetoxyborohydride (2.8 g) and acetaldehyde (572 mg), and the solution was stirred overnight at room temperature. To the reaction solution was added a saturated aqueous solution of sodium bicarbonate, the solution was extracted with ethyl acetate, then washed with 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 (730 mg).
