Versuchsvorschrift

A solution of 1,2-di(4-chlorophenyl)ethan-1-one (known compound) and sodium borohydride in methanol is stirred at ambient temperature for about three hours. After this time, the reaction mixture is cooled, and water is carefully added to destroy excess sodium borohydride. The mixture is cooled to 0° C. and neutralized with concentrated hydrochloric acid. The mixture is concentrated under reduced pressure to remove some of the methanol. The concentrate is taken up in ethyl acetate and washed with an aqueous solution saturated with sodium chloride. The organic layer is dried with sodium sulfate, filtered, and concentrated under reduced pressure, yielding the subject compound.
