Prepared by condensing- p-chloro-o-phenylenediamine with isatin in aequimoleeular proportions in acetic acid solution at the boiling température of the mixture. Light yellow needles or soales from alcohol. M. p. above 300°. Easily soluble in aceton and Chlo- roform. The alcoholic solution yields with ammoniac, silver nitrate solution a red precipitate.
