Ammonia → (2-Methyl-1,3-dioxolan-2-yl)methyl (Z)-3-aminobut-2-enoate

Participants

Reaction Steps

Ammonia gas was passed through a mixture of 19 g of 2,2-ethylenedioxypropyl acetoacetate and 100 ml of methanol for 2.5 hours under ice-cooling while stirring. The solvent was then distilled off and the residue was distilled under reduced pressure to obtain 16 g (84% yield) of 2,2-ethylenedioxypropyl 3-aminocrotonate as a pale yellow oil having a boiling point of 120° C. (5 mmHg).
