Reaction Steps

9.5 g (0.026 mol) of ethyl 2-(4-benzyloxyphenyl)-3-phenylpropionate, 40 ml of toluene and 30 ml of methylene chloride are introduced into a three-necked flask. The mixture is cooled to -70° C. 44 ml of 1M diisobutylaluminium hydride in toluene are added over a period of 15 minutes. The mixture is stirred at that temperature for one hour. 30 ml of methanol and 60 ml of water are added at -70° C. The alumina is filtered off and the aqueous phase is extracted with methylene chloride. The combined organic phases are dried over sodium sulphate and concentrated to dryness. There are obtained 8.2 g of 2-benzyloxyphenyl-3-phenylpropionaldehyde. Yield: 100%.
