Versuchsvorschrift

An improved process for the production of 2-amino-chlorotoluene hydrochloride comprising chlorination of 2-formyl-amino-toluene, splitting off the formyl group of the 2-formyl-amino-chlorotoluenes and isolation of crystalline 2-amino-5-chlorotoluene hydrochloride is disclosed, in which process the 2-formylamino-5-chlorotoluene formed by chlorination of 2-formylamino-toluene in an inert solvent is reacted with methanol to form 2-amino-5-chlorotoluene and methyl formate, and the 2-amino-5-chlorotoluene is isolated as hydrochloride.
