Versuchsvorschrift

2-Chloro-5-nitrotoluene, which is required as a starting product, is accessible by nitrating o-chlorotoluene (Rec. Trav. Chim. Pays-Bas 32, (1913) 244 et seq.). It can be isolated from the resulting mixture of isomers by distillation in 43% yield (Loc. cit. 286). This distillation gives pure 2-chloro-6-nitrotoluene as first runnings the other isomers can be separated in a known way. Since all isomers, by virtue of their reactive groups, are intermediates which can be put to many uses and for which there is adequate demand, no undesirable by-products are obtained in this reaction. Thus, even if this preliminary stage is included, this invention represents a very favorable procedure.
