Reaction Steps

A solution of 0.48 g (13.2 mM) of anhydrous hydrogen chloride in 15 mL of methanol was treated with 0.175 g (0.694 mM) of 5,7-difluoro-2-isopropoxy-1,4-naphthoquinone. The mixture was heated to solvent reflux temperature for 0.33 hours, cooled to room temperature and concentrated in vacuo to give 0.13 g of product. 1H NMR (dmso-d6): δ=7.8 (m, 1H), 7.68 (dd, 1H, JH-Fortho =7.5 Hz), 6.31 (s, 1H), 3.86(s, 3H).
