Participants

Reaction Steps

3-Methylnaphthalen-2-ol (4A) (2.09 g, 13.2 mmol) was taken in acetic acid (50 mL) and bromine (2.11 g) was added to it. The mixture was stirred at room temperature for 20 minutes, concentrated and purified by flash chromatography (silica gel, ethyl acetate/hexanes) to give the desired product (2.7 g, 80%). 1H-NMR: 300 MHz, (CDCl3) δ 7.98 (d, 1 H), 7.60 (d, 1 H), 7.58 (s, 1 H), 7.53 (dd, 1 H), 7.38 (dd, 1 H), 6.05 (s, 1 H), 2.48 (s, 3 H).
