Reaction Steps

A single neck round-bottom flask was charged with 2.3 g of zinc, 0.23 g of HgCl2 and 4 mL of water. Then 37% HCl (0.1 mL) was added and the mixture stirred for 5 minutes. After this, 3 mL of toluene and 3.4 mL of 37% HCl were added and finally 1 g (5.37 mmol) of 1-(2-hydroxynaphthalen-1-yl)ethanone was added portion wise. The resulting mixture was heated at 110° C. for 18 h. The phases were separated and the organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo to afford 780 mg (84% yield) of 1-ethylnaphthalen-2-ol as brown solid.
