Procedure

A solution of 3-fluoro-2-(trifluoromethyl)isonicotinic acid (70.0 mg, 0.335 mmol), {3-[4-(5-fluoro-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-pyrrolo[2,3-b]pyridin-4-yl)-1H-pyrazol-1-yl]-1-piperidin-4-ylazetidin-3-yl}acetonitrile.3[HCl] (207 mg, 0.335 mmol), benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (148 mg, 0.335 mmol) and triethylamine (0.234 mL, 1.68 mmol) in methylene chloride (2 mL) was stirred at room temperature for 1 hour. To the mixture was added trifluoroacetic acid (2 mL, 20 mmol). The resulting solution was stirred at room temperature for 1 hour and concentrated. The residue was dissolved in methanol (2 mL) and ethylenediamine (0.5 mL, 7 mmol). After being stirred at room temperature for 2 hours, the mixture was purified by HPLC (method B) to give 11.2 mg of the title compound as a white solid. LC/MS found: 571.3 (M+H)+. 1H NMR (400 MHz, CDCl3): δ 11.85 (brs, 1H), 8.65 (d, J=4.4 Hz, 1H), 8.59 (s, 1H), 8.23 (d, J=3.2 Hz, 1H), 8.20 (s, 1H), 7.89 (s, 1H), 7.61 (s, 1H), 6.85 (s, 1H), 4.04 (m,1H), 3.72 (m, 2H), 3.58 (m, 2H), 3.53 (m, 2H), 3.53 (m, 2H), 3.40 (m, 1H), 3.25 (m, 1H), 3.06 (t, J=9.2 Hz, 1H), 2.54 (m, 1H), 1.75 (m, 1H), 1.62 (m, 1H), 1.26 (m, 1H), 1.21 (m, 1H).
