Reaction Steps

To a solution of 5-chloro-4-nitro-1-(tetrahydro-2H-pyran-4-yl)-1H-pyrazole (0.4 g, 2 mmol) in ethanol (10 mL) was added ammonium chloride (0.3 g, 5 mmol) and iron (0.3 g). The reaction was stirred at 90° C. for 30 minutes before filtered through celite and concentrated. The residue was triturated in EtOAc and filtered. The filtrated was concentrated to give the title compound (0.34 g, quant.)
