Reaction Steps

To a solution of 2-(4-(5-fluoro-4-(2-(1-hydroxycyclobutyl)thiazol-5-yl)-1H-pyrrolo[2,3-b]pyridin-2-yl)-1H-pyrazol-1-yl)acetic acid (Example 65B) (100 mg, 0.242 mmol) in N,N-dimethylformamide (783 μl) was added 1-methyl-1,4-diazepane (35.9 mg, 0.314 mmol), 4-methylmorpholine (80 μl, 0.726 mmol), 1-hydroxybenzotriazole hydrate (55.6 mg, 0.363 mmol), and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (69.6 mg, 0.363 mmol). The reaction was cooled to room temperature and diluted with dimethyl sulfoxide (1 mL). The resulting solution was purified by reverse phase high performance liquid chromatography (RP HPLC, 19×150 mm Atlantis Prep T3 OBD 5 um column, eluting with a gradient of 5% B in A to 75% B in A over 25 minutes, wherein A is water containing 0.1% v/v trifluoroacetic acid and B is acetonitrile containing 0.1% v/v trifluoroacetic acid) to give the title compound. 1H NMR (300 MHz, DMSO-d6) δ 12.29 (bs, 1H), 8.43 (s, 1H), 8.29 (s, 1H), 8.20 (d, J=3.6 Hz, 1H), 8.10 (s, 1H), 7.05 (s, 1H), 6.65 (s, 1H), 5.22-5.17 (m, 2H), 3.67-3.41 (m, 4H), 2.67-2.34 (m, 6H), 2.32-2.23 (m, 3H), 2.05-1.71 (m, 4H); MS ESI(+) m/z 510.1 [M+H]+.
