N'-benzyl-N-methylethane-1,2-diamine

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 1-benzenesulfonyl-2-bromomethylethylenimine (27.2 g), N-benzyl-N'-methylethylenediamine (16.2 g), triethylamine (19.9 g) and chloroform (350 ml) is refluxed with stirring for 5 hours. The solvent is evaporated under reduced pressure, and the residue is purified by silica gel chromatography to give the title compound (7.9 g) as an oil. is refluxed The solvent is evaporated under reduced pressure the residue is purified by silica gel chromatography

Conditions: temp:50.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a mixture of tris(hydroxymethyl)nitromethane (118.9 g), sodium bicarbonate (40 g) and water (1000 ml), N-benzyl-N'-methylethylenediamine (123 g) is added, and the reaction mixture is heated at about 50° C. for 2 hours. After cooling, the solution is extracted with dichloromethane, and the organic layer is washed with saturated aqueous sodium chloride and dried over magnesium sulfate. The solvent is evaporated under reduced pressure to give 1-benzyl-6-hydroxymethyl-4-methyl-6-nitrohexahydro-1H-1,4-diazepine as an oil. is added After cooling the solution is extracted with dichloromethane the organic layer is washed with saturated aqueous sodium chloride dried over magnesium sulfate The solvent is evaporated under reduced pressure
