Ethyl diethoxyacetate

Anhydrous dimethylamine may be conveniently prepared by allowing 25% aqueous dimethylamine to drop onto solid potassium hydroxide, the gas evolved being dried by passage over solid potassium hydroxide. [Pg.59]

The compound is hygroscopic, and care should be taken to prevent exposure to air. [Pg.59]

Similar procedures for this preparation have been reported by Brown and Short3 and by Copenhaver and Kleinschmidt.4 [Pg.59]

Ethyl diethoxyacetate has been prepared from dichloroacetic acid by the action of sodium ethoxide followed by esterification of the intermediate diethoxyacetic acid. This esterification has been carried out with ethyl iodide on the sodium salt or on the silver salt.5 6 7 It has been more conveniently done with ethanol and acid.8 910 Poorer yields are reported when the dichloroacetic acid is first esterified and then treated with sodium ethoxide.11...
