실험 절차

3-Methylsulfonylamino-5-nitro-1H-indazole can be obtained as described in Example 2 from 0.7 g of 3-amino-5-nitro-1H-indazole, 23 ml of pyridine and 0.455 g of methylsulfonyl chloride. 0.85 g of 3-methylsulfonylamino-5-nitro-1H-indazole is thus obtained in the form of an orange powder used as it is in the following step.
