Reaction Steps

To a suspension of 6-{[2-(3-chloro-pyridin-2-yl)-5-methoxy-2H-pyrazole-3-carbonyl]-amino}-5-methyl-2H-indazole-7-carboxylic acid isopropylamide (0.800 g, 1.71 mmol) in dichloromethane (5.0 mL) was added triethylamine (0.476 mL, 3.42 mmol), followed by methanesulphonyl chloride (0.265 mL, 3.42 mmol). The dark colored homogeneous reaction mixture was stirred for 1 h at 20° C. The reaction mixture was then concentrated in vacuo and the residue was purified by flash-chromatography (SiO2, CH2Cl2/ethyl acetate 4:1) yielding a brown solid that was recrystallized from ethyl acetate to afford the title compound as colourless crystals with a melting range of 135-175° C. (with decomposition).
