The Isolation of N-tert-Butyl-p-Toluidine Hydrochloride and the Synthesis of Mauveine

Abstract

Heating p-toluidine hydrochloride in tert-butanol gave a crystalline precipitate of N-tert-butyl- p-toluidine hydrochloride. This compound, now readily available by this simple procedure, was used to make mauveine, which was found by TLC analysis to be identical to authentic mauveine.
