Reaction Steps

In order to prepare 2-nitro-4-phenylsulfonyloxy-aniline, 15.4 g of 3-nitro-4-amino-phenol in 100 ml of acetone were mixed with 14 ml of triethylamine, and 17.6 g of benzane-sulfonic acid-chloride dissolved in 30 ml of acetone were added dropwise, while stirring, at an internal temperature not exceeding 20° C in an ice bath. The mixture was continued to be stirred for another 3 hours at room temperature, the triethylamine-hydrochloride was filtered off, and the filtrate was evaporated to dryness. The residue was then stirred with 50 ml of methanol and was filtered. After washing with methanol and drying, 18.2 g of 2-nitro-phenylsulfonyloxy-aniline were obtained, which has a melting point of 140° C.
