Versuchsvorschrift

N-[5-(3,5-Difluoro-benzoyl)-1H-indazol-3-yl]-2,2,2-trifluoro-acetamide (19.11 g, 51.76 mmol) in dry dichloromethane (300 mL) was treated with chlorotriphenylmethane (14.72 g, 52.8 mmol) and triethylamine (14.55 mL, 103.5 mmol). After stirring at room temperature for two days, the reaction was washed with a solution of NH4Cl, dried and evaporated. Purification of the crude by chromatography over silica gel (DCM/MeOH) afforded 27.32 g of the title compound (86% yield).
