Reaction Steps

To a solution of 2,4-dichloro-6,7-dihydro-5H-cyclopenta[b]pyridine (0.130 g, 0.69 mmol) in dioxane (3 mL) was added tributyl(furan-2-yl)stannane (0.271 g, 0.76 mmol) and tetrakis(triphenylphosphine)palladium (0.039 g, 0.035 mmol). The mixture was purged with nitrogen and then heated to 110° C. under sealed conditions for 2 h. After this time, the mixture was diluted with water and extracted with ethyl acetate. The organic layer were dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated. The residue was purified by column chromatography (silica, hexanes/ethyl acetate) to afford the title compound (0.140 g, 92%) as a white solid. MW=219.67. 1H NMR (CDCl3, 500 MHz) δ 7.52-7.48 (m, 1H), 7.45 (s, 1H), 7.02-6.98 (m, 1H), 6.52-6.48 (m, 1H), 3.10 (t, J=7.5 Hz, 2H), 2.99 (t, J=7.5 Hz, 2H), 2.15 (quin, J=7.5 Hz, 2H); APCI MS m/z 220 [M+H]+.
