Reaction Steps

In 100 g of pyridine was dissolved 10 g of 2-hydroxydibenzofuran, and the solution was cooled to 0° C. Then, 60 g of a 20% aqueous solution of sodium nitrite was added to the above solution and 100 g of a 30% aqueous solution of sulfuric acid was added dropwise to the mixture while stirring for 10 minutes. After the dropwise addition, the mixture was stirred at 0° C. for 1 hour and then filtered. The recovered solid was washed with water and dried to obtain 11 g of a red crystal of 1-nitroso-2-hydroxydibenzofuran.
