  This invention pertains generally to the field of chemical synthesis and purification, and more specifically to methods of synthesizing and purifying certain 3,7-diamino- phenothiazin-5-ium compounds (referred to herein as "diaminophenothiazinium compounds") including Methylthioninium Chloride (MTC) (also known as Methylene Blue). In one embodiment, the method comprises the steps of, in order: a thiosulfonic acid formation (TSAF) as illustrated below, wherein the reaction is carried out in the presence of a thiosulfate and an oxidizing agent that is or comprises persulfate an oxidative coupling (OC); and a ring closure (RC). The resulting compounds and compositions comprising them (e.g., tablets, capsules) are useful in methods of medical treatment and diagnosis, etc., for example, tauopathies, or Alzheimer's disease (AD).
