Reaction Steps

N-[5-[4-Amino-1-(phenylsulfonyl)-1H-indazol-6-yl]-2-(methyloxy)-3-pyridinyl]methanesulfonamide (700 mg, 1.478 mmol) was dissolved in DCM (30 ml) and cooled to 0° C. before pyridine (0.179 ml, 2.217 mmol) was added. To this mixture was added 2-(chloromethyl)-1,3-thiazole-4-carbonyl chloride (290 mg, 1.478 mmol) as a solution in DCM (10 ml) dropwise over 15 mins. The mixture was stirred at 0° C. for 30 min. Saturated aqueous sodium bicarbonate solution (20 ml) was added to the mixture and it was stirred vigorously for 10 mins. The organic layer was separated using a hydrophobic frit, washed with water (20 ml) and concentrated in vacuo to give the title compound as an orange solid (697 mg).
