反应详情

Lithium aluminum hydride was added to an ice-cooled solution of (2S)-1-benzylpiperidine-2-carboxylic acid methyl ester (178 mg) in tetrahydrofuran (2.7 ml) under nitrogen atmosphere. The mixture was stirred for 2 hours below 5° C. The reaction was quenched by a sequential addition of water (0.12 ml), 15% aqueous sodium hydroxide (0.12 ml) and water (0.36 ml) successively, and the whole was stirred at room temperature for 1 hour. The insoluble materials were removed by filtration. The filtrate was dried over sodium sulfate and evaporated under reduced pressure to give (2S)-1-benzyl-2-(hydroxymethyl)piperidine as a colorless oil.
