Hydrochloric Acid → Ethyl 3-ethoxy-3-iminopropionate hydrochloride

Participants

Reaction Steps

Dry gaseous HCl was passed through a mixture of ethyl cyanoacetate (18 g, 0.185 mol) and ethanol (9.3 mL) in absolute ether (200 mL) over 1 hour. After standing for 48 hours in a refrigerator, the resulting precipitate was filtered off, washed with anhydrous ether, and dried to afford the title compound that was taken directly on to the next step (29 g, 90%).
