実験手順: 4-Fluoro-N-(4-fluoro-benzyl)-benzamide (40.0 grams, 0.16 mole) was dissolved in 240 mL of THF. To this was added BF3.Et2O (7.4 mL. 0.06 mole) and the resulting mixture heated to reflux for 15 min. After cooling to −30° C., BH3.SMe2 (22.3 mL, 0.24 mole) was added using a dropping funnel. The reaction was allowed to warm to room temperature. The reaction flask was fitted with a distillation condenser and solvent removed under reflux for 25 min. The distillation apparatus was replaced with a reflux condenser and the reaction heated to 110° C. for 2 h. After cooling to 0° C., 100 mL of 6N HCl was added and the mixture heated to reflux for 1 hr to yield a thick slurry. 300 mL of 6N NaOH was slowly added at room temperature with intermittent cooling using an ice bath. After all the solid has dissolved Et2O was added and the mixture transferred to a separatory funnel. The organic layer was separated, dried over Na2SO4, filtered and the solvent removed under vacuum to yield an oil. The oil was dissolved in 50 mL of Et2O and 4N HCl (dioxane) added resulting in the formation of a white precipitate which was isolated by filtration to yield 40 grams (93% yield) of bis-(4-fluoro-benzyl)-amine hydrochloride.
