Ammonium Hydroxide → 2,2-Diethoxyacetamide

참여 물질

반응 단계

A mixture of 24.85 g of ethyl diethoxyacetate and 140 ml of concentrated ammonium hydroxide was stirred for 3 hours. The ammonia and H2O were evaporated under reduced pressure on a water bath at 50°-60° leaving a wet solid. The wet solid was dried in a vacuum oven at 53° for 18 hours giving a dark pink solid. The solid was dissolved in CH2Cl2. The solution was filtered to remove a small amount of red insoluble material. The filtrate was concentrated and Skellysolve B was added. Cooling gave 18.0 g (87%) of diethoxyacetamide as orange plates, m.p. 76.5-79°.
