実験手順
To a solution of 3-methoxy-1-aminonaphthalene (U.S. Pat. No. 7,018,431 B2, 0.13 g) in DMF (5 mL), K2CO3 (0.31 g) and iodomethane (0.09 mL) were added. After stirring for 24 hours, the reaction was partitioned between water (30 mL) and EtOAc (30 mL), the layers separated, and the organic layer washed with brine, dried (Na2SO4) and concentrated. The crude reaction purified over silica gel (gradient of EtOAc in heptane) to provide the title compound (0.14 g) as a clear oil: 1H NMR (DMSO-d6) δ 7.99 (d, 1H); 7.74 (d, 1H), 7.40 (ddd, 1H), 7.30 (ddd, 1H), 6.95 (d, 1H), 6.67 (d, 1H), 3.83 (s, 3H), 2.78 (s, 6H); MS expected 202 (C13H16NO, M+1), found 202.
