The combined organic phases were washed with sodium hydroxide (0.2 M, 50 ml), dried (magnesium sulphate), filtered and concentrated in vacuo. Ethanol (75 ml) and hydrazine hydrate (2 equiv.) were added and the mixture was heated to reflux for 2 hours. After cooling the mixture was filtrated and the filter cake washed with DCM (2×50 ml). The filtrate and washings were evaporated and dissolved in ethyl acetate (40 ml). Washing of the organic phase with sodium hydroxide (0.4 M, 2×25 ml) and water (2×25 ml) followed by drying (magnesium sulphate), filtration and evaporation gave 3-(4-chlorophenyl)propylamine. the phases were separated the aqueous phase extracted with DCM (2×50 ml) The combined organic phases were washed with sodium hydroxide (0.2 M, 50 ml) dried (magnesium sulphate) filtered concentrated in vacuo the mixture was heated to reflux for 2 hours After cooling the mixture was filtrated the filter cake washed with DCM (2×50 ml) The filtrate and washings were evaporated dissolved in ethyl acetate (40 ml) Washing of the organic phase with sodium hydroxide (0.4 M, 2×25 ml) and water (2×25 ml) by drying (magnesium sulphate), filtration and evaporation
