Reaction Steps

Into a reaction vial were added 3-[(4-{3-(cyanomethyl)-3-[4-(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]azetidin-1-yl}piperidin-1-yl)methyl]-6-(dimethylamino)-2-fluorobenzonitrile (56 mg, 0.1 mmol), trifluoroacetic acid (1.5 mL) and methylene chloride (1.5 mL). The mixture was stirred at room temperature for 1 hour and concentrated in vacuum. The residue was dissolved in 5 mL of a methanol solution containing 20% ethylenediamine. After being stirred at room temperature for 1 hour, the mixture was purified by HPLC (method B) to give the title compound. LC-MS: 539.2 (M+H)+. 1H NMR (400 MHz, DMSO-d6): δ 12.10 (s, 1H), 8.79 (s, 1H), 8.67 (s, 1H), 8.39 (s, 1H), 7.59 (d, J=3.6 Hz, 1H), 7.42 (t, J=8.8 Hz, 1H), 7.05 (d, J=3.6 Hz, 1H), 6.78 (d, J=8.8 Hz, 1H), 3.68 (d, J=8.4 Hz, 2H), 3.51 (m, 4H), 3.38 (s, 2H), 3.01 (s, 6H), 2.67 (m, 2H), 2.17 (m, 1H), 1.97 (m, 2H), 1.63 (m, 2H), 1.15 (m, 2H).
