Process for producing N,O-diacetyl-6-amino-2-naphthol |
| abstract |
N,O-diacetyl-6-amino-2-naphthol is produced by subjecting 2-naphthyl acetate to a Fries rearrangement or 2-naphthol and an acetylating agent to a Friedel-Crafts acetylation to form 6-hydroxy-2-acetonaphthone which is then reacted as is or as its acetate ester with hydroxylamine or a hydroxylamine salt to form 6-hydroxy-2-acetonaphthone oxime. The oxime is then subjected to a Beckmann rearrangement and accompanying acetylation with acetic anhydride to form the N,O-diacetyl-6-amino-2-naphthol. |
