Reaction Steps

A solution of 31.64 g(0.2 mol) ethyl butyryl acetate and 5 mol of ethanol is added dropwise over a period of 5 min. to a solution of 38.7 g(0.6 mol) ethylamine (70% in water) and 50 ml of water (exotherm from 28° C. to 33° C. observed). The mixture is stirred at room temperature for 18 hrs. and is extracted with three 100 ml portions of methylene dichloride (MDC). The methylene dichloride extract is dried over magnesium sulfate and concentrated in vacuo to afford 30.7 g(83% yield) of product, a colorless oil.
