2,4-Difluorobenzenesulfonyl chloride (0.048 mL, 0.354 mmol) was added dropwise to a solution of 5-[4-(5-{[(2R,6S)-2,6-dimethyl-4-morpholinyl]methyl}-1,3,4-oxadiazol-2-yl)-1-(phenylsulfonyl)-1H-indazol-6-yl]-2-(methyloxy)-3-pyridinamine (185 mg, 0.321 mmol) in pyridine (1 ml). The mixture was stirred at room temperature for 2 h. 2,4-Difluorobenzenesulfonyl chloride (0.048 mL, 0.354 mmol) was added dropwise and the mixture continued stirring at room temperature for 1 h. Water (10 ml) was added and the resultant brown precipitate collected by filtration and dried in the vacuum oven for 72 h to give the title compound as a brown solid (194 mg).
