Procedure

A mixture of 6-{[2-(3-chloro-pyridin-2-yl)-5-methoxy-2H-pyrazole-3-carbonyl]-amino}-5-methyl-2H-indazole-7-carboxylic acid isopropylamide (500 mg, 1.07 mmol) and K2CO3 (196 mg, 1.6 mmol) in THF (5 mL) was stirred for 1 hour at ambient temperature, and was treated with propargylbromide (120 μL, 1.6 mmol). The resulting reaction mixture was stirred for 24 hours at 60° C. AcOEt and water was added. The phases were separated. The aqueous layer was extracted with AcOEt. The organic layers were washed with water, combined, dried over MgSO4 and concentrated in vacuo. Purification of the residue by flash-chromatography (SiO2, Toluene/AcOEt 7:3) afforded the title compound as a colorless crystalline solid. LC/MS: 506 (M+H)+, 528 (M+Na)+.
