Reaction Steps

N-{6-[5-{[(2,4-Difluorophenyl)sulfonyl]amino}-6-(methyloxy)-3-pyridinyl]-1-[(4-methylphenyl)sulfonyl]-1H-indazol-4-yl}-2-{[(2R,6S)-2,6-dimethyl-4-morpholinyl]methyl}-1,3-thiazole-4-carboxamide (105 mg) was dissolved in IPA (1 mL) and 2M NaOH (aq) (1 mL) and stirred at room temperature overnight. The IPA was evaporated and the remaining aqueous phase was diluted with water (2 ml), then acidified to ca. pH 4 using 2M HCl (aq) to give a precipitate that was extracted into DCM, passed through a hydrophobic frit, then evaporated to dryness. The residue was purified by ISCO companion 12 g silica cartridge using a 0-6% methanol in DCM gradient over 16 mins at 30 ml/min. Product containing fractions were combined, evaporated to dryness then further dried on a vacuum line to give title compound, (53 mg).
