Abstract

306,607. Carpmael, A., (I. G. Farbenindustrie AKt.-Ges.). Nov. 18, 1927. Divided on 306, 575. o-Aminomercapto-, o-aminothioglycollic and ocyanothioglycollic-aryl derivatives.-An o-aminoarylsulphocyano compound, in which the position para to the amino group is occupied or forms part of a further ring, prepared for example according to Specifications 257,619 and 303,813, is treated with alkali, preferably in the presence of a reducing agent, so as to saponify the sulphocyano group and form a mercapto group. The latter is coupled with chloracetic acid and the resulting o-aminoarylthioglycollic acid is finally diazotized and subjected to Sandmeyer's reaction in order to obtain an o-cyanoarylthioglycollic acid. In examples, 1-methyl-2-amino-3-sulphocyano-5-chlorbenzene, 1-amino-2-sulphocyano-4- ethoxybenzene and l-sulphocyano-2-aminonaphthalene are used as starting materials, 1-methyl- 2-cyano-5.chlorbenzene-3-thioglycollic acid, 1- cyano-4-ethoxybenzene-2-thioglycollic acid and 2- cyanonaphthalene-1-thioglycollic acid respectively being produced. Specification 11173/06 also is referred to.
