Reaction Steps
76.2 g (0.342 mol) of 6-bromo-β-naphthol were suspended in 385 ml of 90%-strength acetic acid and nitrosated for two hours at 4° C. with 28.5 g (0.413 mol) of sodium nitrite in 230 ml of water, and stirring was then continued for 23 h at room temperature. The suspension was then made up to twice its volume by filling up with water and the product formed was filtered off by suction. After drying, 83.8 g (97.3%) of crude 1-nitroso-6-bromo-β-naphthol whose purity is adequate for the further reaction was obtained.
