실험 절차

A mixture of 4-chloro-2-(3-chlorophenyl)-6,7-dihydro-5H-cyclopenta[b]pyridine hydrochloride (0.070 g, 0.23 mmol), (3-(3-hydroxypropyl)phenyl)boronic acid (0.054 g, 0.30 mmol), 2M Na2CO3 (0.5 mL), and Pd(PPh3)4 (0.013 g, 0.012 mmol) in dioxane (50 mL) was heated at reflux under nitrogen for 2.5 h. After this time, the mixture was diluted with ethyl acetate (100 mL), washed with water (100 mL), dried (Na2SO4), filtered, and concentrated. The resulting residue was purified by silica gel chromatography eluting with 20% ethyl acetate/hexanes to 100% ethyl acetate to afford the free base of title compound (0.028 g, 34%) as a white foam. This material was redissolved in Et2O (20 mL) and 4N HCl in dioxane (0.1 mL) added. The mixture was concentrated, triturated with Et2O, and lyophilized with a water/acetonitrile/methanol mixture to afford the title compound as a white solid. MW=363.88. 1H NMR (DMSO-d6, 300 MHz) δ 8.21 (s, 1H), 8.12-8.08 (m, 1H), 7.92 (s, 1H), 7.58-7.33 (m, 6H), 3.45 (t, J=6.4 Hz, 2H), 3.16-3.01 (m, 4H), 2.74-2.69 (m, 2H), 2.19-2.08 (m, 2H), 1.83-0.83 (m, 2H); APCI MS m/z 364 [M+H]+.
