実験手順
A catalytic amount of sodium methoxide (enough to insure a basic solution) was added to a solution of 2-(3-(dimethylamino)phenoxy)ethyl acetate (39A) (0.545 g, 2.44 mmol) in anhydrous MeOH (7 mL). The reaction mixture was stirred at rt for 2.5 hours before a small amount of acidic resin (Dowex 50WX8-200) was added. The reaction mixture was filtered, concentrated under reduced pressure and the crude material was purified by column chromatography on silica gel eluting with a gradient of PE:EtOAc 66:34-50:50, to provide the desired compound 2-(3-(dimethylamino)phenoxy)ethanol (39B).
