Procedure
A solution of (3S)-3-benzyloxycarbonylamino-2-piperidone (2.48 g, 9.99 mmol) in tetrahydrofuran (25 mL) was cooled at an external temperature of −78° C., followed by adding dropwise thereto an n-butyllithium-hexane solution (1.54 M, 6.2 mL, 9.548 mmol) over a period of 10 minutes, and the resulting mixture was stirred at the same temperature for 1.5 hours. Subsequently, a solution of phosphorus oxychloride (1.53 g, 9.98 mmol) in tetrahydrofuran (5 mL) was added thereto and stirred for 1.25 hours, after which n-hexylamine (d=0.76, 6.0 mL, 45.06 mmol) was added thereto and the resulting mixture was stirred at room temperature for 10 minutes.
