Procedure

To a stirred room temperature solution of 6-bromo-1-(4-fluoro-phenyl)-1H-indazole-4-carboxylic acid (0.25 g, 0.70 mmol) in DMF (15 mL) was added PyBOP (0.45 g, 0.90 mmol) and triethylamine (0.20 g, 1.6 mmol). After 15 minutes, 4-aminomethyl-N-methyl-benzenesulfonamide (0.15 g, 0.7 mmol) was added. After 5 hours, the reaction was quenched with water (30 mL), and extracted with ethyl acetate (30 mL). The combined organic layers were washed with brine (30 mL) and dried over sodium sulfate and concentrated in vacuo. The residue was purified by silica gel chromatography eluting with a gradient of 30-50% ethyl acetate in hexanes to afford the title compound.
