{5-[5-(2-chloro-4-pyrimidinyl)-2-(1-methylethyl)-1,3-thiazol-4-yl]-2-fluorophenyl}amine (160 mg, 0.459 mmol) was dissolved in DMF (3 mL) and added pyridine (0.074 mL; 0.917 mmol). The reaction was stirred 5 min and added 1-methylimidazole-4-sulfonyl chloride (83 mg, 0.459 mmol). The reaction mixture was heated at 45° C. for two days. The reaction mixture was cooled to rt, added silica gel, and concentrated. The crude product was chromatographed on silica gel eluting with 100% DCM to 100% EtOAc to obtained the title compound as a white solid (150 mg, 66% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 10.12 (br. s., 1H), 8.49 (d, J=5.4 Hz, 1H), 7.52-7.83 (m, 2H), 7.51 (d, J=1.8 Hz, 1H), 7.28-7.43 (m, 1H), 7.25 (t, J=9.3 Hz, 1H), 7.05 (d, J=5.3 Hz, 1H), 3.58 (s, 3H), 3.00-3.23 (m, 1H), 1.35 (d, J=6.9 Hz, 6H).
