실험 절차

N-{5-[4-Amino-1-(phenylsulfonyl)-1H-indazol-6-yl]-2-chloro-3-pyridinyl}methanesulfonamide (780 mg, 1.632 mmol) was dissolved in DCM (32 ml) and pyridine (0.198 ml, 2.448 mmol) and cooled to 0° C. To this was added 2-(chloromethyl)-1,3-thiazole-4-carbonyl chloride (320 mg, 1.632 mmol) as a solution in DCM (6 ml) dropwise. The reaction was left to warm up and after final addition was stirred for a further 66 h at 20° C. Reaction was incomplete so the mixture was cooled again to 0° C. and a further portion of 2-(chloromethyl)-1,3-thiazole-4-carbonyl chloride (320 mg, 1.632 mmol) as a solution in DCM (6 ml) was added dropwise. The reaction was left to warm up and was stirred for a further 23 h at 20° C. Reaction still incomplete so, the mixture was cooled again to 0° C. and a further portion of 2-(chloromethyl)-1,3-thiazole-4-carbonyl chloride (320 mg, 1.632 mmol) as a solution in DCM (6 ml) was added dropwise. The reaction was left to warm up and was stirred for a further 23 h at 20° C. The solution was treated with DCM (25 ml) and saturated aqueous sodium bicarbonate (25 ml) and stirred vigorously for 10 mins. The organic phase was then separated, washed with dilute aqueous sodium chloride (30 ml), passed through a hydrophobic frit, and loaded directly onto a 100 g silica cartridge. This was eluted with 0-100% ethyl acetate/cyclohexane over 60 mins using the Flashmaster II. Appropriate fractions were combined and evaporated to give the title compound as a yellow solid (321 mg).
