Procedure

To a solution of 2-Chloro-N-[6-(2-phenylchroman-6-yloxy)-pyridin-3-yl]-acetamide (200 mg) in acetonitrile was added potassium carbonate (133 mg) and 2,5-dimethylpyrrolidine (81 μl). The mixture was stirred at room temperature. Water was added to the reaction mixture. Solution was extracted with ethyl acetate. Organic extract was dried and evaporated. The product was purified by column chromatography using gradient elution with methanol-dichloromethane (2%->5%). 1H-NMR (300 MHz; d6-DMSO) δ: 9.66 (s, 1H), 8.35 (d, 1H, J 2.7 Hz), 8.06 (dd, 1H, J 2.7, 8.8 Hz), 7.47-7.32 (m, 5H), 6.93 (d, 1H, J 8.8 Hz), 6.88-6.84 (m, 3H), 5.12 (dd, 1H, J 2.1, 9.9 Hz), 3.22 (s, 2H), 3.05-2.88 (m, 1H), 2.78-2.66 (m, 3H), 2.22-2.12 (m, 1H), 2.08-1.92 (m, 1H), 1.90-1.79 (m, 2H), 1.43-1.34 (m, 2H), 1.06 (d, 6H, J 6.1 Hz).
