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

实验步骤: 59.9 g (412.6 mM) of ethyl(ethylamino)(oxo)acetate and 45 ml (412.6 mM) of (2,2-dimethoxyethyl)amine, in 480 ml of 2-propanol, were stirred at room temperature for 16 h. A white precipitate was filtered, washed with 2-propanol and dried under vacuum to give 67.8 g of N-(2,2-dimethoxyethyl)-N′-ethylethanediamide. A white precipitate was filtered washed with 2-propanol dried under vacuum

实验步骤: To 135,8 ml (1000 mM) of diethyloxalate and 1 g of aliquat 336, in 1000 ml of dichloromethane, were added 64 ml (1000 mM) of ethylamine at 70% in water. The reaction mixture was stirred at room temperature for 72 h. The reaction mixture was dried over anhydrous sodium sulfate and the solvent was removed under vacuum to give an oil, which was further purified by silica gel column chromatography, using dichloromethane/dimethylketone (95/5) as eluant, to give 59.9 g of ethyl(ethyl amino)(oxo)acetate as an oil. The reaction mixture was dried over anhydrous sodium sulfate the solvent was removed under vacuum to give an oil, which was further purified by silica gel column chromatography
