Eugenol-acetamid is prepared as follows: Monochloracetic acid is acted upon by eugenol sodium, when eugenol acetic acid results. This acid is treated with alcohol and hydrochloric acid, by which it is converted into the "ethylester of eugenol-acetic acid. Strong alcoholic ammonia converts this into eugenol-acetamid. As crystallized from water it occurs in lustrous scales; from alcohol in fine needles; melting at 110°."
It is claimed for eugenol-acetamid, that when it is applied in the form of a fine powder, it produces local anaesthesia without any caustic action, similar to cocaine. It has been successfully employed as a local anaesthetic in the treatment of wounds; and is also recommended as an obtundent in the extraction of teeth.
