実験手順
To a solution of 500 mg (2.61 mmol) of 6-amino-1H-indazole-7-carboxylic acid methyl ester, prepared as in step a in example 10, in 5 mL of acetonitrile is added 1.29 g (5.73 mmol) of N-iodosuccinimide. The reaction mixture is stirred at ambient temperature for 1 hour and at 50° C. for 6 hours. The solvent is then evaporated and the residue is suspended in water. Filtration affords 750 mg (91%) of the product as a brown solid; LC/MS:318/319 (M+H)+.
