Vorschrift

30% w/v Aqueous hydrogen peroxide solution (1.5 ml.) is added to a solution of 2'-chloro-4'-nitro-5-(2,4,5-trichlorophenylthio)-3-t-butyl-6-methylsalicylanilide (0.4 g.) in acetic acid (15 ml.) at 50°-60° C. The mixture is heated at 95°-100° C. for 30 minutes and is then poured into ice cold water (200 ml.). The precipitated solid thus obtained is crystallised twice from acetic acid to give 2'-chloro-4'-nitro-5-(2,4,5-trichlorophenylsulphinyl)-3-t-butyl-6-methylsalicylanilide, m.p. 245°-246° C.
