Abstract

L'invention concerne un procédé pour produire des éthers 4-amino-1-naphtol, selon lequel on produit d'abord des éthers de naphtol à partir de 1-naphtols, puis ces éthers de naphtol sont transformés en éthers 4-acétamino-1-naphtol correspondants, et ensuite, le groupe acyle est séparé. La présente invention porte également sur des éthers 4-acétamino-1-naphtol.
