N'-benzylbutane-1,4-diamine

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

実験手順: To a suspension of 1.1 g of lithium aluminum hydride in 50 ml of tetrahydrofuran was added slowly 2.9 g of N-(3-cyanopropyl)benzylamine (obtained in Reference Example 4) at room temperature. The reaction mixture was heated gently under reflux for 15 minutes and then allowed to cool. To the mixture was added dropwise and carefully 2.2 ml of water and then 1.8 ml of 10% aqueous sodium hydroxide. The resultant precipitate was filtered off, the filtrate was dried over anhydrous sodium sulfate and the solvent was distilled off under reduced pressure to give 1.7 g of N-benzyl-1,4-butanediamine as a colorless oil. The reaction mixture was heated gently under reflux for 15 minutes to cool To the mixture was added dropwise The resultant precipitate was filtered off the filtrate was dried over anhydrous sodium sulfate the solvent was distilled off under reduced pressure
