Versuchsvorschrift

To a suspension of lithium aluminum hydride (0.76 g, 20 mmol) in cyclopentylmethylether (20 mL) was added a solution of 3-benzylamino-butyric acid ethyl ester (2.10 g, 9.5 mmol) in cyclopentylmethylether (10 mL) dropwise at 0° C. under nitrogen atmosphere. The resulting mixture was warmed to room temperature and stirred for 3 hours. Then small amount of sodium sulfate saturated aqueous solution was added dropwise to quench the reaction at 0° C. and stirred for one hour. The resulting solid material was removed by filtration and the organic solution was concentrated to yield 3-benzylamino-butan-1-ol (1.49 g, 8.3 mmol, 87%) as colorless oil. The oil was used in the subsequent step without further purification.
