Reaction Steps

Trans-2-(4-((2-(3-chlorophenyl)-6,7-dihydro-5H-cyclopenta[b]pyridin-4-yl)amino)cyclohexyl)acetonitrile hydrochloride (0.056 g, 0.14 mmol) was suspended in sulfuric acid (2 mL) at 0° C. The reaction was warmed to rt and stirred for 16 h. After this time, the mixture was added dropwise to a saturated NaHCO3 solution, extracted with ethyl acetate, dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated. The residue was purified by column chromatography (silica, dichloromethane/methanol), followed by formation of the hydrochloride salt to afford the title compound (0.048 g, 82%) as a white solid. MW=420.38. 1H NMR (DMSO-d6, 500 MHz) δ 13.50 (s, 1H), 7.99-7.96 (m, 1H), 7.86-7.82 (m, 1H), 7.71-7.67 (m, 1H), 7.62-7.58 (m, 2H), 7.27 (s, 1H), 7.10 (s, 1H), 6.73 (s, 1H), 3.89-3.79 (m, 1H), 3.06 (t, J=7.5 Hz, 2H), 2.78 (t, J=7.5 Hz, 2H), 2.17 (quin, J=7.5 Hz, 2H), 1.96 (d, J=7.0 Hz, 2H), 1.92-1.85 (m, 2H), 1.78-1.71 (m, 2H), 1.70-1.60 (m, 1H), 1.50-1.38 (m, 2H), 1.21-1.09 (m, 1H); APCI MS m/z 384 [M+H]+.
