2-(叠氮甲基)-4-苄基吗啉

反应条件: temp:-5.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of 2-azidomethyl-4-benzylmorpholine (15 g) in toluene (40 ml) is added dropwise to a stirred solution of 70% sodium bis(2-methoxyethoxy)aluminum hydride in toluene (60 ml) cooled to -5° C. The reaction mixture is stirred at 25° C. for 1.5 hours and cooled to 10° C., and the excess of the reducing agent is decomposed by the cautious addition of 10% aqueous sodium hydroxide solution. The organic layer is separated, washed successively with water and saturated aqueous sodium chloride solution, and dried over magnesium sulfate. After removal of the solvent under reduced pressure, the title compound is obtained a an oil (11 g). cooled to 10° C. The organic layer is separated washed successively with water and saturated aqueous sodium chloride solution dried over magnesium sulfate After removal of the solvent under reduced pressure

反应条件: temp:130.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of 4-benzyl-2-chloromethylmorpholine (15.0 g), sodium azide (8.6 g), and dimethylformamide (150 ml) is stirred at 130° C. for 2 hours. The reaction mixture is diluted with water and extracted with diethyl ether. The organic layer is washed successively with water and saturated aqueous sodium chloride solution, and dried over magnesium sulfate. The solvent is distilled off under reduced pressure to give 2-azidomethyl-4-benzylmorpholine (15 g) as an oil. extracted with diethyl ether The organic layer is washed successively with water and saturated aqueous sodium chloride solution dried over magnesium sulfate The solvent is distilled off under reduced pressure
