Procedure

A 100-mL, one-neck, round bottomed flask equipped with a magnetic stirrer was charged with compound 126 (370 mg, 0.68 mmol), potassium carbonate (235 mg, 1.70 mmol), and DMF (4 mL). The resulting mixture was stirred for 5 min, and methyl iodide (435 mg, 3.10 mmol) was then added. After stirring for a further 1 h at ambient temperature, the reaction mixture was evaporated to dryness under reduced pressure. The residue was purified by column chromatography to give an 82% yield of compound 127 as a light yellow oil. 1H NMR (CD3OD) δ (ppm) 8.20 (m, 2H), 6.99-7.66 (m, 7H), 5.58 (s, 2H), 5.15 (bs, 1H), 3.62 (dt, 2H, J=1.8, 8.0 Hz), 3.32 (s, 3H), 2.78 (s, 3H), 1.55 (m, 3H), 0.88 (m, 2H), −0.07 (s 9H); m/z=558 (M+H).
