Reaction Steps

N-{3-[5-(2-Chloro-4-pyrimidinyl)-2-(1,1-dimethylethyl)-1,3-thiazol-4-yl]-2-fluorophenyl}-1-methyl-1H-pyrazole-5-sulfonamide (530 mg, 1.04 mmol) and ammonium hydroxide (26%, 15 ml) was heated in a steel reactor to 100° C. for 3 h. The reaction mixture was cooled and concentrated under reduced pressure, the residue was dissolved in methanol, and purified by Pre-HPLC (A=10 m MNH4HCO3/H2O, B=Acetonitrile), then the white solid obtained was dissolved in EtOAc, treated with HCl (g) for 30 min. The mixture was concentrated under reduced pressure, and then the residue was suspended in ether (20 ml), treated with ultrasonic for 3 min, filtered, the solid was suspended in ether (20 ml) again, treated with ultrasonic for 3 min, filtered to afford the title compound was obtained as a white solid (142 mg, 26%). 1HNMR (MEOD-d4): δ ppm 8.05 (br s, 1H), 7.61-7.65 (ddd, J1=7.7 Hz, J2=1.6 Hz, 1H), 7.42-7.46 (m, 2H), 7.32-7.36 (t, J=8.0 Hz, 1H), 6.70-6.71 (d, J=2.0 Hz, 1H), 6.25-6.27 (d, J=6.4 Hz, 1H), 4.04 (s, 3H), 1.50 (s, 9H). MS: 488.2 [M+H]+.
