Methoxyphenamine was first synthesized at the Upjohn company by Woodruff and co-workers.[3] A later synthesis by Heinzelman, from the same company, corrects the melting point given for methoxyphenamine hydrochloride in the earlier paper, and describes an improved synthetic procedure, as well as resolution of the racemic methoxyphenamine.[4]
