Reaction Steps

3.15 g (13.9 mmol) of 3-cyclopentyl-4-nitro-isoxazole-5-carboxamide (example V) and 17.51 g (327 mmol) of ammonium chloride are suspended in 70 ml of water and the suspension is cooled to 0° C. 8.5 g (118 mmol) of zinc powder are added in small portions while stirring vigorously. The reaction mixture is stirred at room temperature for 30 minutes. For the working up, filtration takes place through kieselguhr with the kieselguhr subsequently being washed with ethyl acetate, and the filtrate is evaporated to dryness in vacuo. The residue is triturated with ethyl acetate. After filtering, the solvent is removed in vacuo. 1.95 g (70%) of colorless solid are obtained.
