Reaction Steps
To a 0° C. solution of diethylamine (1819 mL) and triethylamine (25.5 mL) in 500 mL of methylene chloride was added dropwise, with stirring, 25 g of acetoxyacetyl chloride. The ice bath was removed, and the mixture allowed to warm to 20° C. while stirring for an additional 2 hr. After filtration to remove amine hydrochloride salts, the methylene chloride solution was evaporated under reduced pressure to provide 29.1 g of crude, N,N-diethylacetoxyacetamide, as a yellow oil. The yellow oil was dissolved in 125 mL of methanol and 168 mL of 1N sodium hydroxide added with stirring. A slight exotherm was noted, and the mixture was allowed to stir for 2 hr. without further warming. Solvents were removed under reduced pressure to 1/4 volume, and the remaining aqueous solution extracted with ethyl acetate (200 ml). The ethyl acetate extract was dried over anh. sodium sulfate, and evaporated under reduced pressure to provide 14.0 g of N,N-diethylglycolamide as a yellow oil.
