Versuchsvorschrift
A solution of 0.054 mmol of ammonia in ethanol was added dropwise to 0.054 mol of ethyl 2-acetamidoacetoacetate in 40 ml of ice cold ethanol over a period of 10 minutes. The reaction vessel was tightly capped and allowed to stir overnight at 23° C., after which the solvent was removed at reduced pressure to provide ethyl 2-acetamido-3-aminobut-2-enoate in a 3/1 ratio of two geometrical isomers.
