The resulting mixture was hydrogenated using a balloon. After 1 h the contents of the reaction flask were filtered through Celite® and the filtrate evaporated under reduced pressure. Flash column chromatography (methylene chloride:methanol:ammonium hydroxide, 90:10:1) gave [3-Fluoro-4-(2-phenylethoxy)cyclohexyl]amine as a waxy oil (0.519 g, 85% yield).
