Reaction Steps

N-{3-[5-(2-Chloro-4-pyrimidinyl)-1,3-thiazol-4-yl]phenyl}-2,6-difluorobenzenesulfonamide (0.1 g, 0.2 mmol) was taken up in 2 mL NH4OH and heated to 140° C. for 20 min in a microwave reactor. The solvent was removed under reduced pressure and the residue was taken up in EtOAc and washed with 2 mL of 0.1 N HCl (aq). The organic layer was dried over Na2SO4 and evaporated onto silica gel. Purification by ISCO chromatography (0 to 50% EtOAC in DCM) afforded the title compound (62 mg, 0.139 mmol, 64.7% yield) as a yellow solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 11.00 (s, 1H), 9.16 (s, 1H), 7.94 (d, J=5.1 Hz, 1H), 7.59-7.69 (m, 1H), 7.32 (t, J=7.9 Hz, 1H), 7.16-7.27 (m, 5H), 6.78 (s, 2H), 5.99 (d, J=5.3 Hz, 1H). MS (ESI): 446 [M+H]+.
