Procedure:
To a solution of furan-3-carboximidamide hydrochloride (2.00 g, 13.6 mmol) and perchloromethyl mercaptan (1.47 ml, 13.6 mmol) in dichloromethane (40 ml) was added dropwise a solution of sodium hydroxide (2.72 g, 68.0 mmol) in water (6 ml) under ice-cooling. Then, the reaction mixture was stirred under ice-cooling for 1 hour and at room temperature for 1 hour. The organic layer was separated, washed with water, and then dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography (hexane:ethyl acetate=9:1) to give 0.82 g (32.2%) of the desired product as an oil.

Procedure:
Hydrazine hydrate (0.56 mL, 12 mmol) was added to a solution of Example 3A (820 mg, 3.0 mmol) in chloroform (37 mL) and methanol (4 mL). The suspension was stirred at room temperature for 22 hours. Silica gel (10 g) was added, and the mixture was concentrated to dryness. The residue was applied to the top of a flash chromatography column and eluted with hexanes-ethyl acetate (80:20) to provide the title compound as the free amine. The residue was dissolved in ethanol (5 mL) and treated with HCl/dioxane (4M, 1 mL). The solution was heated at reflux and diluted with gradual addition of ethyl acetate (50 mL). The mixture was cooled to room temperature and filtered to provide the title compound as a hydrochloride salt. 1H NMR (300 MHz, CD3OD) δ 7.15-7.22 (m, 2 H), 7.42-7.49 (m, 2 H).

Procedure:
3,5-Diamino-4-[(3-ethylphenyl)hydrazono]pyrazole was prepared using 99 mg (0.5 mmol) of 2-[(3-ethylphenyl)hydrazono]malononitrile, which was derived from 3-ethylaniline (124 μL, 1.0 mmol) and malononitrile (1.5 mmol) as described in Example 8, and hydrazine hydrate. Precipitate formed in the reaction tube approximately 10 min after the addition of hydrazine hydrate. The resulting solid was isolated by filtration, precipitated from an ethyl acetate solution by the addition of hexanes, and dried to yield 12 mg (10%) of the title compound as a yellow solid.
