Participants

Reaction Steps

11.64 g (0.04 mol) of 2-(N-2-phenetylcarbamoyl)-1-naphthol was dissolved in a mixture composed of 12 g of potassium hydroxide, 25 ml of water and 200 ml of methanol. To the resulted solution, an aqueous solution of diazonium salt prepared with using 5.75 g of anthranilic acid was added to 0° to 5° C. After stirred at 5° to 10° C. for 30 minutes, 100 ml of a 20% aqueous solution of potassium hydroxide was added thereto and 50 g of sodium hydrosulfite was added at 50° to 60° C.
