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 4-hydroxypiperidine (62 mg). 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. Product was purified by column chromatography using 10% methanol in methylene chloride as eluant. 2-(4-Hydroxypiperidin-1-yl)-N-[6-(2-phenyl-chroman-6-yloxy)-pyridin-3-yl]-acetamide was isolated as its hydrochloride salt. 1H-NMR (400 MHz; d4-MeOH) δ: 8.41 (s, 1H), 8.06 (dd, 1H, J 2.7, 9.0 Hz), 7.45-7.28 (m, 5H), 6.95-6.85 (m, 4H), 5.10 (dd, 1H, J 2.1, 10.0 Hz), 4.13 (s, 2H), 3.72-3.68 (m, 1H), 3.48-3.43 (m, 3H), 3.25-3.10 (m, 1H), 3.02-2.97 (m, 1H), 2.81-2.75 (m, 1H), 2.26-1.76 (m, 6H). (M)+=459 (5.8%), 360 (7.4%), 114 (100%).
