Reaction Steps
3-[2-(1,1-dimethylethyl)-5-(2-methyl-4-pyrimidinyl)-1,3-thiazol-4-yl]-2-fluoroaniline (70 mg, 0.204 mmol), 3-fluorobenzenesulfonyl chloride (40 mg, 0.204 mmol), and pyridine (0.162 mg, 2.04 mmol) were dissolved in dichloromethane (2 mL). After 2 h stirring, the reaction mixture was placed on silica gel and chromatography (0 to 30% EtOAc/Hexanes over 25 min.) to obtain N-{3-[2-(1,1-dimethylethyl)-5-(2-methyl-4-pyrimidinyl)-1,3-thiazol-4-yl]-2-fluorophenyl}-3-fluorobenzenesulfonamide (83 mg, 81%). 1H NMR (400 MHz, DMSO-d6) δ ppm 10.41 (s, 1H), 8.42 (d, J=5.49 Hz, 1H), 7.58-7.52 (m, 2H), 7.50-7.42 (m, 2H), 7.39-7.31 (m, 2H), 7.24 (t, J=7.87 Hz, 1H), 6.57 (d, J=5.31 Hz, 1H), 2.52 (s, 3H), 1.37 (s, 9H); MS (ESI); 499 (M−H)−.
