were first synthesized. The definitive synthesis, which involves treating anhydrous codeine base with nicotinic anhydride at 130 °C, was published by Pongratz and Zirm in ''Monatshefte für Chemie'' in 1957, simultaneously with the two analogues in an article about amides and esters of various organic acids. Nicocodeine is almost always used as the hydrochloride salt, which has a free base conversion ratio of .917. In the past, the tartrate, bitartrate, phosphate, hydrobromide, methiodide, hydroiodide, and sulfate were used in research or as pharmaceuticals.
