     Mix, in a mortar, the benzene solution of benzenesulfochlorid with a slight excess of anilin; (add the latter gradually and work up the mass well) add water to dissolve out the anilin hydrochlorid formed and if the solid separates well, pour off the liquid, if not, first distill off the benzene. Wash out the excess of anilin by means of dilute HCl. Purify the product, by dissolving it in twice molecular NaOH or KOH and reprecipitate with HCl, or by simply washing with gasoline. The product recrystallized from alcohol melts at 108 degrees.
