Participants

Reaction Steps

Following a procedure analogous to the procedure described in Example 21 using N-{3-[5-(2-chloro-4-pyrimidinyl)-2-(4-morpholinyl)-1,3-thiazol-4-yl]-2,4-difluorophenyl}-2,5-difluorobenzenesulfonamide (150 mg, 0.256 mmol) and NH4OH (2.5 mL, 17.97 mmol) heated in a microwave reactor at 130° C. for 30 min the title compound was obtained as a light yellow solid (127 mg, 83% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 10.74 (br. s., 1H), 7.90 (d, J=5.3 Hz, 1H), 7.46-7.58 (m, 4H), 7.25 (t, J=8.8 Hz, 1H), 6.62 (br. s., 2H), 5.61 (d, J=5.1 Hz, 1H), 3.69-3.74 (m, 4H), 3.42-3.47 (m, 4H). MS (ESI): 566 [M+H]+.
