Versuchsvorschrift

To a stirred solution of 1-(4-fluoro-phenyl)-1H-indazole-4-carboxylic acid (0.05 g, 0.2 mmol) in DMF (10 mL) was added PyBOP (0.14 g, 0.30 mmol) and triethylamine (0.07 g, 0.6 mmol) at room temperature. After 15 minutes, 4-aminomethyl-N-methyl-benzenesulfonamide (0.04 g, 0.2 mmol) was added. After 5 hours, the mixture was quenched with water (30 mL) and diluted with ethyl acetate (30 mL). The organic layer was separated, washed with brine (30 mL), dried over sodium sulfate, filtered and concentrated. The residue was purified by silica gel chromatography eluting with a gradient of 0-30% ethyl acetate in hexanes to afford the title compound.
