2-(Tributylstannyl)-furan (0.4 mL, 1.29 mmol)) was added slowly to a solution of 2-bromo-6-methoxy-1-(methoxymethoxy)-3-methylnaphthalene (14 (0.4 g, 1.29 mmol) in toluene (10 mL). Reaction mixture was heated at 105° C. A portion (0.01 g) of tetrakis(triphenylphosphino)palladium (0) (0.061 g, 0.053 mmol) was added every 1 h until reaction was complete. Reaction mixture was cooled to RT then diluted with Et2O and water. The layers were separated and the organic layer was washed with brine, dried over MgSO4, filtered and concentrated. The crude oil was purified with a gradient of 20% EtOAc in hexanes to give 0.29 g (76%) of the title compound (213) as oil. 1H NMR (400 MHz, d-CDCl3): δ 2.36 (s, 3H), 3.37 (s, 3H), 3.93 (s, 3H), 4.85 (s, 2H), 6.49-6.50 (m, 1H), 6.53-6.55 (m, 1H), 7.05 (m, 1H), 7.11 (dd, J1=2.4 Hz, J2=9.2 Hz, 1H), 7.39 (s, 1H), 7.58-7.58 (m, 1H), 8.08 (d, J=9.2 Hz, 1H).
