Reaction Steps

A mixture of 7-cyano-2-naphthol (22.3 g, 131.8 mmol), sodium carbonate (29.3 g, 277 mmol) and I2 (31.8 g, 125.2 mmol) in water (500 mL) and THF (80 mL) at 0° C. was stirred at room temperature for 3 h, acidified with 1M HCl and extracted with ethyl acetate. The extracts were washed with saturated Na2S2O3 and brine, dried (Na2SO4) and concentrated. The product was recrystallized from ethyl acetate to yield 33 g of the title compound.
