Versuchsvorschrift

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 NaH (60%) (67 mg, 1.6 mmol) in THF (5 mL) was stirred for 1 hour at ambient temperature, and was treated with 2,2,2-trifluoroethyl trifluoromethanesulfonate (246 mg, 1.06 mmol). The resulting reaction mixture was stirred for 4 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. M.p. 178-181° C., LC/MS: 550 (M+H)+, 572/574 (M+Na)+.
