Reaction Steps

To a suspension of N-{3-[5-[2-(aminomethyl)-4-pyrimidinyl]-2-(4-morpholinyl)-1,3-thiazol-4-yl]-2-fluorophenyl}-2,5-difluorobenzenesulfonamide (0.1 g, 0.178 mmol) in dichloromethane (0.500 ml) was added pyridine (0.036 ml, 0.444 mmol) and a solution of methane sulphonyl chloride (0.025 g, 0.222 mmol) in dichloromethane (0.2 ml) and stirred overnight. The reaction was concentrated. The crude product was added to a silica gel column and eluted with DCM with MeOH (0% to 10%) and collected fractions to obtain crude product. The crude product was treated with EtOAc and hexanes and sonicated to form a white solid. The solid was filtered to obtain 2,5-difluoro-N-{2-fluoro-3-[5-(2-{[(methylsulfonyl)amino]methyl}-4-pyrimidinyl)-2-(4-morpholinyl)-1,3-thiazol-4-yl]phenyl}benzenesulfonamide (38 mg, 33%) as white solid. MS (ESI): 641 [M+H]+.
