Reaction Steps

3.59 g of 3-bromo-3-(4'-fluoro-4-biphenylyl)butylamine hydrochloride [obtainable by reacting 3-hydroxy-3-(4'-fluoro-4-biphenylyl)-butyramide with PBr3 to give 3-bromo-3-(4'-fluoro-4-biphenylyl)-butyramide and reduction with LiAlH4 ] are dissolved in a mixture of 15 ml of acetone and 15 ml of water, 1 drop of sulfuric acid is added, and the mixture is warmed to 45° for 4 hours and worked up in the customary manner to give 3-(4'-fluoro-4-biphenylyl)-3-hydroxybutylamine, m.p. 144°-146°. A little 3-(4'-fluoro-4-biphenylyl)-2-butenylamine, which can be removed by chromatography (over SiO2), is formed as a by-product.
