Procedure

To a solution of 2-chloro-N-[6-(2-phenylchroman-6-yloxy)-pyridin-3-yl]-acetamide (177 mg) in acetonitrile was added potassium carbonate (118 mg) and 33% dimethylamine in ethanol (480 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. 2-Dimethylamino-N-[6-(2-phenyl-chroman-6-yloxy)-pyridin-3-yl]acetamide was isolated as its hydrochloride salt. 1H-NMR (300 MHz; d6-DMSO) δ: 11.3 (s, 1H), 8.41 (d, 1H, J 2.3 Hz), 8.07 (dd, 1H, J 2.3, 8.8 Hz), 7.47-7.33 (m, 5H), 7.00 (d, 1H, J 8.8 Hz), 6.88-6.85 (m, 3H), 5.12 (d, 1H, J 8.5 Hz), 4.20 (s, 2H), 3.01-2.69 (m, 8H), 2.20-1.91 (m, 2H).
