Sodium Sulfate → 2Acetamido-2-{2-[4-(1,1-ethylenedioxy-5-phenylpentyl)phenyl]ethyl}propane-1,3-diol

Participants

Reaction Steps

A solution of lithium aluminum hydride (2.0 g) in tetrahydrofuran (100 ml) was dropwise added a solution of diethyl 2-acetamido-2-{2-[4-(1,1-ethylenedioxy-5-phenylpentyl)phenyl]ethyl}malonate (14.0 g) in tetrahydrofuran (50 ml) at 3-13° C. over 30 minutes, and the mixture was stirred at room temperature for 2 hours. To the reaction mixture was dropwise added a saturated aqueous sodium sulfate solution (27 ml), and the mixture was stirred at room temperature for an hour. The precipitate was filtered through celite and the filtrate was concentrated under reduced pressure to give a colorless transparent oily substance was purified by silica gel column chromatography (eluent; chloroform:methanol=20:1) to give 2acetamido-2-{2-[4-(1,1-ethylenedioxy-5-phenylpentyl)phenyl]ethyl}propane-1,3-diol (5.8 g) as a colorless transparent oily substance.
