反応条件: temp:70.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 4-Fluoropiperidine HCl (801 mg, 5.74 mmol) was added dropwise to a stirred aqueous solution of glycolonitrile (647 uL of a 52% aqueous solution, 6.31 mmol) at 5° C. Sodium carbonate (912 mg, 8.60 mmol) was added and the solution was stirred at 70° C. for 1.5 h. The solution was cooled, diluted with water (2 mL), washed with Et2O (3×4 ml). The organic fraction was dried and the solvent evaporated to give 2-(4-fluoropiperidin-1-yl)acetonitrile as a colourless oil. The oil was then dissolved in a 7 N solution of ammonia in MeOH (25 mL) and submitted to hydrogenation on the H-Cube using 75 bar of hydrogen pressure at 55 C with a flow rate of 0.8 mL/min and using a Raney nickel catalyst cartridge. After the reaction was complete the solvent was stripped in vacuo to give 2-(4-fluoropiperidin-1-yl)ethanamine as a translucent oil. The solution was cooled washed with Et2O (3×4 ml) The organic fraction was dried the solvent evaporated
