Abstract
The hydrochloride of 5-chloro-2-toluidine is obtained by dispersing 2-toluidine hydrochloride in a halohydrocarbon and reacting it with chlorine. No isomers are formed and very little higher chlorinated products. 5-chloro-2-toluidine is easily set free from the hydrochloride with aqueous bases.
