| Product | 1-Amino-4-cyano-2-naphthol | HCID 170839 | 55.2% |
Reaction Steps
30 g (0.46 mol) of potassium cyanide are added to a solution of sodium 4-(2-hydroxy-1-naphthylazo)benzenesulfonate (10 g, 28.5 mmol) in 120 ml of water. After 2 days at 90° C., the mixture is filtered and the filtrate is saturated with carbon dioxide. The yellow precipitate is filtered off to give 2.9 g (55%) of 4-cyano-2-hydroxynaphthylamine (V).
