To a 50-mL polypropylene vial (Note 1) are added 0.839 g (2.67 mmol) of 2-[ethyl[4-[(lE)-(4-nitrophenyl)azo]phenyl]amino]ethanol (Disperse Red 1, Note 2), 0.985 g of (2.39 mmol) N-[(9H-fluoren-9-ylmethoxy)carbonyl]-L-aspartic acid,l-(l, 1-dimethylethyl) ester (Fmoc-L-Asp-OtBu, Note 3), 3.26 g (4.73 mmol) of polystyrylsulfonyl chloride resin (Note 4), and 30 mL anhydrous methylene chloride (Note 5). The vial is capped and the mixture is shaken for five min (Note 6). N-Methylimidazole (0.764 mL, 9.58 mmol) is then added to the deep red mixture (Note 7) and the resulting mixture is shaken for 2 hr (Note 8).

Synthesis of N,N,-bis(4-nitrophenyl)-N, N -bis[4-(2-phenyl-2-isopropyl) phenyl]- ,4-phenylene-diamine (3). In a 250 ml three neck round-bottom lisk was placed bis- [4-(2-pheiiyl- 2-isopropyl)phenyl]-4-aminopheitylamine (2) (7.26 g, 14.63 mmol), 4-Qtoro-nitro- benzene (4.13 g, 29.27 mmol), cesium Qioride (4.41 g, 29.27 mmol), and 80 ml DMSO. The mixture was heated with stirring at 120"C for 24 hr. The reaction mixture was cooled and then poured into 500 ml methanol. The red precipitate was collected by titration and dried under vacuum. The product was puriffed by sihca gel colunrn chromatography ( -hexane dichloromethane = 1 1) to afford dinitio compoimd (3) in a 65% yield mp 224-225 "C (by DSC 10°C /min).

Hydrazides are formed by the acylation of hydrazines, and have a C-N bond of rather low chemical stability toward hydrolysis. It is, therefore, not surprising that the cleavage of this bond represents a major metabolic pathway for most hydrazides. The reaction is catalyzed by amidases since it can be inhibited by O-ethyl 0-(4-nitrophenyl) phenyl phosphothionate or bis(4-nitrophenyl) phosphate, which are classical inhibitors of this enzyme. 

N-(4-nitrophenyl)-amino acids N-(2,4-dinitrophenyl)-amino acids 8) and 3-nitro-2-pyridyl amino acids have been of considerable interest. A generally applicable mechanistic scheme does not exist so far, and except for 3-nitrophenyl acetate in ortho and/or -para position of the phenyl (pyridyl) ring seems to be a prerequisite for efficient decarboxylation.
