Reaction Steps

6-(Chloromethyl)-N-[6-{6-(methyloxy)-5-[(methylsulfonyl)amino]-3-pyridinyl}-1-(phenylsulfonyl)-1H-indazol-4-yl]-2-pyridinecarboxamide (50 mg, 0.08 mmol) was dissolved in MeCN (0.5 ml). Thiomorpholine 1,1-dioxide (available from TCI-Europe) (14 mg, 0.1 mmol) was dissolved in MeCN (0.3 ml) and added to the mixture, followed by DIPEA (0.026 ml, 0.15 mmol) and sodium iodide (0.012 g, 0.078 mmol) (heaped microspatula). The solution was stirred and heated to 70° C. for 18 hr. Potassium trimethylsilanolate (64 mg, 0.5 mmol) was dissolved in THF (0.4 ml) and added to the mixture which was then heated at 50° C. for 5 h. The solution was quenched with aqueous MeCN (50:50, 1 ml) and neutralised, then the solvents were removed in a blowdown unit. The residue was dissolved in DMSO (0.5 ml) and purified by MDAP (Method D). The solvent was evaporated using the Genevac to give the title compound (5 mg).
