To a solution of 6-aminonaphth-1-ol (1.0 g) in DMF (50 mL), NaH (60% in mineral oil, 0.17 g) was added, and the reaction was stirred for 1 hour. Iodomethane (0.39 mL) was added, and the reaction was stirred for another 1 hour. The reaction was then partitioned between NaHCO3 (aq., 150 mL) and EtOAc (100 mL), the layers separated, and the organic layer washed with brine, dried (Na2SO4) and concentrated. The crude reaction was purified over silica gel (gradient of EtOAc in heptane) to provide the title compound (0.8 g) as an orange oil:: 1H NMR (DMSO-d6) δ 7.81 (d, 1H); 7.16 (dd, 1H), 7.04 (d, 1H), 6.85 (dd, 1H), 6.75 (d, 1H), 6.53 (dd, 1H), 5.32 (s, 2H), 3.86 (s, 3H).
