Procedure
To a solution of {3-[2-(4-fluoro-phenylsulfanylmethyl)-3-methyl-benzofuran-4-yloxy]-propyl}-pyridin-3-ylmethyl-amine (16 mg) and bis(2,4-pentanedionato)-vanadium oxide (9.8 mg) in dichloromethane (2 ml) was added 30% hydrogenperoxide aqueous solution (20 μl) at room temperature and the mixture was stirred for 1 hour. After the addition of ammonia solution (2 ml) the whole mixture was vigorously stirred until the sticky precipitation disappeared, then extracted with ethyl acetate, washed with brine and dried over anhydrous sodium sulfate. The mixture was separated by silica gel column chromatography developed by dichloromethane and methanol. {3-[2-(4-fluoro-benzenesulfinylmethyl)-3-methyl-benzofuran-4-yloxy]-propyl}-pyridin-3-ylmethyl-amine (5 mg) was obtained as a white solid: ESI-MS: m/z 453 (MH+); 1H-NMR (CDCl3): δ 1.98 (3H, s), 2.00-2.09 (2H, m), 2.85 (2H, t, J=6.9 Hz), 4.01 (1H, d, J=13.5 Hz), 4.13 (2H, t, J=5.9 Hz), 4.32 (1H, d, J=13.5 Hz), 6.59 (1H, d, J=7.9 Hz), 6.94 (1H, d, J=8.2 Hz), 7.10-7.25 (4H, m), 7.44-7.49 (2H, m), 7.65-7.69 (1H, m), 8.49-8.59 (2H, m). {3-[2-(4-fluoro-benzenesulfonylmethyl)-3-methyl-benzofuran-4-yloxy]-propyl}-pyridin-3-ylmethyl-amine (11 mg) was obtained as a colorless oil:. ESI-MS: m/z 469 (MH+); 1H-NMR (CDCl3): δ 1.99-2.09 (2H, m), 2.12 (3H, s), 2.86 (2H, t, J=7.3 Hz), 3.84 (2H, s), 4.13 (2H, t, J=5.9 Hz), 4.50 (2H, s), 6.59 (1H, d, J=8.3 Hz), 6.89 (1H, d, J=8.2 Hz), 7.11-7.69 (7H, m), 7.69-8.57 (2H, m).
