実験手順: To a stirring suspension of N-{3-[(Z)-2-(2-chloro-4-pyrimidinyl)-1-hydroxyethenyl]phenyl}-2,6-difluorobenzenesulfonamide (1.0 g, 2.36 mmol, 1.0 eq) in DCM (˜5 mL) was added NBS (0.44 g, 2.48 mmol, 1.05 eq). Upon formation of a red solution (˜10 minutes) the reaction mixture was concentrated to a solid and taken up in dioxane (10 mL). To this solution was added MgCO3 (0.38 g) followed by 1-pyrrolidinecarbothioamide (0.384 g, 2.95 mmol, 1.25 eq). After stirring 3 h, the mixture was quenched with water (50 mL) and 1N HCl (10 mL) and stirred 0.25 h. The mixture was filtered and the resultant solid triturated with EtOAc/Hexanes to give 0.52 g (41%) of the title compound. 1H-NMR (400 MHz, DMSO-d6) δ ppm 11.11 (s, 1H), 8.14 (d, J=5.7 Hz, 1H), 7.65-7.74 (m, 1H), 7.41 (t, J=7.7 Hz, 1H), 7.18-7.29 (m, 5H), 6.44 (d, J=5.5 Hz, 1H), 3.45-3.52 (m, 4H), and 1.98-2.05 (m, 4H). Upon formation of a red solution (˜10 minutes) the reaction mixture was concentrated to a solid To this solution was added MgCO3 (0.38 g) the mixture was quenched with water (50 mL) and 1N HCl (10 mL) stirred 0.25 h The mixture was filtered the resultant solid triturated with EtOAc/Hexanes
