A solution of 1-(5-(5-fluoro-2-(3-(methylsulfonyl)phenyl)-1-tosyl-1H-pyrrolo[2,3-b]pyridin-4-yl)thiazol-2-yl)cyclobutanol (Example 91A) (94.2 mg, 0.158 mmol) in methanol (2.500 mL) and 2N sodium hydroxide solution (833 μL) was heated by microwave irradiation (Biotage, Initiator) to 120° C. for 30 minutes. The reaction was cooled to room temperature, and the pH adjusted to ˜3 with 10% aqueous HCl solution. The resulting solution was purified by reverse phase high performance liquid chromatography (RP HPLC, 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 ammonium acetate and B is acetonitrile) to give the title compound. 1H NMR (300 MHz, DMSO-d6) δ ppm 12.73 (b s, 1H), 8.60 (b s, 1H), 8.57 (s, 1H), 8.39 (d, J=8.85 Hz, 1H), 8.38 (d, J=3.51 Hz, 1H), 7.91 (d, J=7.78 Hz, 1H), 7.78 (t, 1H), 7.56 (s, 1H), 3.33 (s, 3H), 2.64-2.59 (m, 2H), 2.45-2.37 (m, 2H), 2.03-1.93 (m, 2H); MS ESI(+) m/z 443.9 [M+H]+.
