Reaction Steps

To a solution of tert-butyl 4-(4-((4-(2-hydroxyethyl)phenyl)amino)-6,7-dihydro-5H-cyclopenta[b]pyridin-2-yl)piperazine-1-carboxylate (0.026 g, 0.059 mmol) in methylene chloride (5 mL) was added TFA (0.1 mL). The mixture stirred at rt for 16 h and purified by preparative HPLC (water/acetonitrile with 0.05% TFA), followed by formation of the hydrochloride salt to afford the title compound (0.010 g, 41%) as a yellow-brown solid. MW=411.37. 1H NMR (DMSO-d6, 500 MHz) δ 13.21 (s, 1H), 9.46-9.19 (m, 3H), 7.31 (d, J=8.0 Hz, 2H), 7.25 (d, J=8.0 Hz, 2H), 6.04 (s, 1H), 3.68-3.56 (m, 6H), 3.20 (br s, 4H), 3.05-2.96 (m, 2H), 2.81-2.72 (m, 4H), 2.19-2.10 (m, 2H); APCI MS m/z 339 [M+H]+.
