's production begin with either Phenyl-2-Propanone (P2P) or with ephedrine or pseudoephedrine. The principal methods used are the Nagai method, Birch's reduction or the semplifyed shake'n'bake.

31/12/2017 · The Birch Reaction: Methamphetamine from (pseudo)ephedrine

Though dating back to the discovery of the drug, the Nagai route did not become popular among illicit manufacturers until ca. 1982, and comprised 20% of production in Michigan in 2002 It involves red phosphorus and (also known as hydroiodic acid or iohydroic acid). (The hydrogen iodide is replaced by iodine and water in the "Moscow route") The hydrogen iodide is used to reduce either ephedrine or pseudoephedrine to methamphetamine. On heating the precursor is rapidly iodinated by the hydrogen iodide to form iodoephedrine. The phosphorus assists in the second step, by consuming iodine to form phosphorus triiodide (which decomposes in water to phosphorous acid, regenerating hydrogen ). Because hydrogen iodide exists in a chemical equilibrium with iodine and , the phosphorus reaction shifts the balance toward hydrogen production when iodine is consumed. In Australia, criminal groups have been known to substitute "red" phosphorus with either hypophosphorous acid or phosphorous acid (the "Hypo route"). This is a hazardous process for amateur chemists because phosphine gas, a side-product from in situ hydrogen iodide , is extremely toxic to inhale. The reaction can also create toxic, flammable white phosphorus waste. Methamphetamine produced in this way is usually more than 95% pure.

Methamphetamine is most structurally similar to methcathinone and amphetamine. Synthesis is relatively simple, but entails risk with flammable and corrosive chemicals, particularly the solvents used in extraction and purification; therefore, illicit production is often discovered by fires and explosions caused by the improper handling of volatile or flammable solvents. The six major routes of production begin with either phenyl-2-propanone (P2P) or with one of the isomeric compounds pseudoephedrine and ephedrine.
