Procedure

Into a saturated ammonia-methanol solution (60 ml) was added 4-chloro-3-nitro-N-(pyridin-3-ylmethyl)benzenesulfonamide (2.77 g), followed by about 2 days of heating at 100° C. in a sealed tube. After the reaction, the solvent was evaporated under reduced pressure and the formed yellow crystals were collected by filtration and dried to obtain 4-amino-3-nitro-N-(pyridin-3-ylmethyl)benzenesulfonamide (2.51 g). Hereinafter, the compound of Reference Examples 26 was obtained similarly.
