実験手順

A mixture of 5-(2-chloro-4-fluorophenyl)-1,3-dimethyl-4-nitro-1H-pyrazole (i.e. the product of Step A) (0.2 g, 0.74 mmol), iron powder (0.2 g, 3.6 mmol) and saturated aqueous ammonium chloride solution (1 mL) in ethanol (5 mL) was heated at 80° C. for 4 h. After cooling to room temperature, the reaction mixture was diluted with ethyl acetate and filtered through a pad of Celite® (diatomaceous earth) on a sintered glass frit funnel. The filtrate was concentrated under reduced pressure and the resulting material was purified by silica gel column chromatography (ethyl acetate as eluant) to provide the title compound (0.14 g).
