A suspension of N-{3-[5-(2-chloro-4-pyrimidinyl)-2-(4-morpholinyl)-1,3-thiazol-4-yl]-2-fluorophenyl}-3-pyridinesulfonamide (195 mg, 0.366 mmol) and ammonia in i-PrOH 2M (8 mL, 16.0 mmol) was heated in a sealed tube at 100° C. overnight. The reaction mixture was evaporated onto silica gel and chromatographed (10-100% 1:9 MeOH:EtOAc in DCM). The title compound was obtained as a yellow solid after trituration in diethyl ether (88 mg, 45% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 10.56 (s, 1H), 8.84 (d, J=1.7 Hz, 1H), 8.75 (dd, J=4.7, 1.0 Hz, 1H), 7.99-8.15 (m, 1H), 7.82 (d, J=5.3 Hz, 1H), 7.55 (dd, J=7.9, 5.0 Hz, 1H), 7.33-7.46 (m, 1H), 7.24 (d, J=6.3 Hz, 2H), 6.55 (br. s., 2H), 5.56 (d, J=5.2 Hz, 1H), 3.59-3.72 (m, 4H), 3.34-3.49 (m, 4H). MS (ESI): 514.1 [M+H]+.
