A solution of tert-butyl 3-(5-fluoro-4-(2-(1-hydroxycyclobutyl)thiazol-5-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridin-2-yl)-5-methoxy-1H-indole-1-carboxylate (Example 93B) (140 mg, 0.203 mmol) in methanol (2.00 mL) and 2N sodium hydroxide solution (670 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 12.19 (bs, 1H), 11.52 (s, 1H), 8.48 (s, 1H), 8.21 (d, J=2.0 Hz, 1H), 8.04 (d, J=2.0 Hz, 1H), 7.46 (d, J=2.0 Hz, 1H), 7.41 (d, J=3.51 Hz, 1H), 7.01 (s, 1H), 6.89 (d, J=3.51 Hz, 1H), 6.68 (s, 1H), 3.87 (s, 3H), 2.64-2.55 (m, 2H), 2.45-2.35 (m, 2H), 2.05-1.92 (m, 2H); MS ESI(+) m/z 435.0 [M+H]+.
