Reaction Steps

N-[6-[5-Amino-6-(methyloxy)-3-pyridinyl]-2-(tetrahydro-2H-pyran-2-yl)-2H-indazol-4-yl]-2-{[(2R,6S)-2,6-dimethyl-4-morpholinyl]methyl}-1,3-thiazole-4-carboxamide (250 mg) was dissolved in DCM (6 ml) and N-methylmorpholine (0.143 ml) was added. The reaction was cooled to 0° C. in an ice bath, then 2-chloroethanesulfonyl chloride (0.047 ml) was added dropwise. The reaction was left to warm to RT overnight. Reaction had blown dry, so was redissolved in DCM (6 ml). Further 2-chloroethanesulfonyl chloride (0.047 ml) was added and stirred at RT for 2 hours. Water (6 ml) was added to the reaction. The DCM was separated, passed through a hydrophobic frit, then evaporated to dryness to give crude title compound (250 mg) used directly in the next step without further purification.
