==Preparation==
Dulcin can be produced by the addition of [[potassium cyanate]] to [[p-Phenetidine|''p''-phenetidine]] [[hydrochloride]] in an [[aqueous solution]] at room temperature.<ref>{{Cite journal | journal = [[Medicinal Chemistry Research]] | volume = 11 | issue = 9 | pages = 481–503 | date = 2003 | title = Synthesis of sulofenur analogs as antitumour agents: Part II | author = Youssef, Khairia M. | author2 = Al-Abdullah, Ebtihal | author3 = El-Khamees, Hamad }}</ref>

An alternate way to make dulcin is by mixing [[urea]] and ''p''-phenetidine hydrochloride to a mixture of [[hydrochloric acid]] and glacial [[acetic acid]].<ref>{{Cite journal | journal = Org.
