Synthesis of some heteronuclear mono- and di-chloro-2-naphthylamines
Abstract
Improved methods of preparation of 6- and 7-chloro-2-naphthylamine from sodium 2-naphthol-6-sulphonate and disodium naphthalene-2,7-disulphonate, respectively, are described. Syntheses of 5,6-, 5,7-, and 6,7-dichloro-2-naphthylamines are also reported.
