Procedure

N-[5-[4-(5-{[(2R,6S)-2,6-dimethyl-4-morpholinyl]methyl}-1,3-oxazol-2-yl)-1-(phenylsulfonyl)-1H-indazol-6-yl]-2-(methyloxy)-3-pyridinyl]-2,4-difluorobenzenesulfonamide (105 mg, 0.140 mmol) was suspended in isopropanol (2 ml) and 2M sodium hydroxide (aq) (0.699 ml, 1.399 mmol) added. The reaction mixture was stirred at RT for 2 h, the solvent removed under a stream of nitrogen and the residue dissolved in water (1 ml) and acidified to pH˜6 by the addition of 2M hydrogen chloride (aq)(a black precipitate formed). The suspension was extracted with dichloromethane (3×2 ml) and the combined organics dried to give a brown solid. This was combined with the black precipitate which remained insoluble in the extraction, dissolved in MeOH:DMSO (1 ml, 1:1, v/v) and purified by MDAP (method A). The appropriate fractions were concentrated in vacuo to give the title compound as a white solid (20 mg). LCMS (Method A): Rt 0.69 mins, MH+ 611.
