Reaction Steps

7.3 g of sodium borohydride, which has been dissolved in a little 10% strength sodium hydroxide solution are added to a solution of 150 g of E-2-(4-fluorophenyl)-3-(2-chlorophenyl)-propenal (prepared as described in Example A) in 600 ml of isopropanol at 0° C. After the reaction mixture has been stirred for two hours at room temperature, 300 ml of water are added to the solution and the resulting emulsion is extracted by shaking with methylene chloride. The organic phase isolated is then dried over sodium sulfate and evaporated down. 150.7 g (100%) of E-2-(4-fluorophenyl)-3-(2-chlorophenyl)-prop-2-enol are obtained.
