Versuchsvorschrift

A mixture of 54 g (0.15 mole) of 5-chloro-2'-fluoro-2-iodobenzophenone and 28.4 g (0.75 mole) of sodium borohydride in 1000 ml of ethanol was stirred at 0° C. for 15 min. The solution was diluted with water and extracted with ether. The ether solution was washed with water, dried over anhydrous sodium sulfate, and concentrated at reduced pressure to give a deep yellow oil.
