4-(octahydrocyclopentane[c]pyrrolylmethyl)-phenyl-1,2-diamine (4.0 g, 17.32 mmol), 4-nitro-1H-pyrazole-3-carboxylic acid (2.47 g) , 17.32mmol), EDC \u00a1\u00a4 HCl (4.98g, 19.05mmol) and HOBt (3.4g, 19.05mmol) was dissolved in dry DMF (25mL) are stirred at room temperature overnight. The solvent was removed under reduced pressure, was added glacial acetic acid (40 mL), heated to reflux for 3h, the solvent was removed under reduced pressure, purified through the column, and then washed with methanol, methanol-insoluble product as a yellow solid that is, to give a yellow solid (0.90 g, 23.94percent).<\/p>\n
