Reaction Steps

A solution of crude tert-butyl 2-((4-(5-chloropyridin-3-yl)-2-((S)-2-(fluoromethyl)pyrrolidin-1-yl)-3-((trans-4-methylcyclohexyl)methyl)-3H-imidazo[4,5-c]pyridin-6-yl)(imino)methyl)hydrazinecarboxylate (19.0 mg, 0.032 mmol) in acetonitrile (793 μL) was stirred at 80° C. for 72 hr. Purification of the reaction by mass triggered reverse phase HPLC (C-18), eluting with acetonitrile/water containing 0.1% TFA afforded 5-{4-(5-chloropyridin-3-yl)-2-[(2S)-2-(fluoromethyl)pyrrolidin-1-yl]-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridin-6-yl}-2,4-dihydro-3H-1,2,4-triazol-3-one (TFA salt). 1H NMR (600 MHz, CD3OD) δ 8.83 (d, J=1.8 Hz, 1H), 8.72 (d, J=2.3 Hz, 1H), 8.38 (t, J=2.1 Hz, 1H), 7.96 (s, 1H), 4.70 (dd, J=3.3, 9.9 Hz, 0.5H), 4.65-4.51 (m, 2H), 4.45 (dd, J=4.1, 9.9 Hz, 0.5H), 3.90 (dd, J=8.4, 14.9 Hz, 1H), 3.85-3.74 (m, 2H), 3.55 (dd, J=6.0, 14.9 Hz, 1H), 2.32-2.24 (m, 1H), 2.19-2.11 (m, 1H), 2.05-1.93 (m, 2H), 1.50-1.42 (m, 2H), 1.27-1.19 (m, 1H), 1.15-1.04 (m, 1H), 1.04-0.97 (m, 1H), 0.73 (d, J=6.6 Hz, 3H), 0.72-0.63 (m, 1H), 0.63-0.50 (m, 4H).
