Reaction Steps

Following general procedure B2, 4-chloro-2-(3-chlorophenyl)-6,7-dihydro-5H-cyclopenta[b]pyridine hydrochloride (0.075 g, 0.25 mmol) was reacted with 2-(5-aminopyridin-2-yl)ethanol (0.045 g, 0.33 mmol), followed by formation of the hydrochloride salt to afford the desired product (0.023 g, 21%) as a white solid. MW=438.78. 1H NMR (DMSO-d6, 500 MHz) δ 14.38 (s, 1H), 10.12 (s, 1H), 8.72 (s, 1H), 8.10 (s, 1H), 7.98-7.95 (m, 1H), 7.78 (d, J=7.5 Hz, 1H), 7.71-7.58 (m, 3H), 7.21 (s, 1H), 3.80 (t, J=8.0 Hz, 2H), 3.20 (t, J=8.0 Hz, 2H), 3.03 (t, J=7.5 Hz, 2H), 2.98 (t, J=7.5 Hz, 2H), 2.26 (quin, J=7.5 Hz, 2H); APCI MS m/z 366 [M+H]+.
