Reaction Steps
1.03 g of sodium borohydride was added to 4.84 g of 4,4'-dimethoxybenzophenone in 80 ml of ethanol, followed by stirring for 7 hours at room temperature. Next, after adding water and stirring for 30 minutes, the solution was concentrated to roughly 20 ml. Moreover, ethyl acetate and water were added and after extracting with ethyl acetate (50 ml×3), the product was washed with saturated brine and dried with anhydrous sodium sulfate. The solvent was distilled off under reduced pressure to obtain 4.84 g of the target compound. Yield: 99%
