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-fluorophenyl}-1-piperidinesulfonamide (190 mg, 0.352 mmol) and NH4OH (4 mL) in a microwave reactor for 75 min at 120° C., the title compound was obtained an off-white solid (75 mg, 41% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 9.69 (s, 1H) 7.83 (d, J=5.3 Hz, 1H) 7.51 (td, J=7.4, 2.2 Hz, 1H) 7.05-7.38 (m, 2H) 6.54 (s, 2H) 5.79 (d, J=5.3 Hz, 1H) 3.68 (t, J=4.7 Hz, 4H) 3.43 (t, J=4.6 Hz, 4H), 3.01 (t, J=5.0 Hz, 4H) 1.33-1.52 (m, 6H). MS (ESI): 520.0 [M+H]+.
