Participants

Reaction Steps

To a stirred and cooled (0° C.) mixture of 2.57 parts of intermediate 8, namely N-[4-[1-(1H-imidazol-1-yl)butyl]phenyl]acetamide and 23.0 parts of concentrated sulfuric acid were added portionwise 1.01 parts of potassium nitrate. Upon complete addition, stirring was continued for 30 minutes at 0° C. The reaction mixture was poured into crushed ice and treated with ammonium hydroxide to pH 10. The product was extracted with trichloromethane. The extract was dried, filtered and evaporated, yielding 3 parts (99.4%) of N-[4-[1-(1H-imidazol-1-yl)butyl]-2-nitrophenyl]acetamide as a residue (interm. 9).
