実験手順
15.6 g of 2-amino-5-(4-fluorophenylsulfonyloxy)nitrobenzene were combined with 20.7 g imidazole in 100 ml dimethylformamide in a round bottom flask. The reaction mixture was heated to reflux for 3 hours and then cooled to room temperature. Reaction mixture was then precipitated by addition of water filtered and precipitate was washed with water and dried. Residue was resolubilized in hot ethyl glycol, crystallized by cooling and the crystals were washed with methanol and dried, yielding 10.4 g of 2-amino-5-(4-[1-imidazolyl]-phenylsulfonyloxy)nitro-benzene (melting point 209° C.).
