Reaction Steps
To a solution of (4-benzyloxy-6-fluoro-naphthalen-2-yl)-acetic acid methyl ester (876 mg, 2.7 mmol) in methanol (20 mL) was added 10% palladium on carbon (132 mg). The resulting mixture was stirred vigorously under a hydrogen atmosphere (balloon) overnight and then filtered. The filtrate was concentrated in vacuo to give (6-fluoro-4-hydroxy-naphthalen-2-yl)-acetic acid methyl ester (601 mg, 95%) as a white solid. 1H NMR (400 MHz, CDCl3) δ ppm 7.69-7.76 (m, 2H), 7.30 (s, 1H), 7.22-7.26 (m, 1H), 6.82 (s, 1H), 3.74 (s, 3H), 3.72 (s, 2H).
