Procedure:
A solution of 2-fluoro-5-nitro-benzoic acid (3.702 g, 20 mmol) in anhydrous methanol (10.00 mL) was treated with 98% sulphuric acid and the solution was heated to reflux for 4 hours. The solvent was removed under vacuum and the residue was dissolved in ethyl acetate (50 mL). The solution was washed with saturated aqueous sodium bicarbonate (3×10 mL), brine until neutrality ant then water, and dried over anhydrous sodium sulphate. The solvent was removed under vacuum to afford a thick oil that started to crystallize, After adding n-hexane (3 mL) the crude was stored for 2 days in the fridge. The crystalline compound was filtered and washed with n-hexane to yield 3.147 g of the pure compound.

Oxalyl dichloride (38.7 μl, 0.444 mmol) and N,N-dimethylformamide (about 1 μl) were added to a solution of the 1H-indazole-5-carboxylic acid (40.0 mg, 0.247 mmol) obtained in Reference Example 1 in dichloromethane (2.5 ml), and the resulting mixture was stirred at room temperature for 0.5 hour and then was stirred with heating under reflux for 2 hours while maintaining the temperature. The reaction solution was concentrated to dryness and a solution of the resulting residue in tetrahydrofuran (1.5 ml) was added dropwise to a solution of 1-phenylcyclohexylamine (130 mg, 0.742 mmol) in tetrahydrofuran (2.0 ml). The resulting mixture was stirred for 18 hours while being maintained at room temperature. A 5% aqueous sodium bicarbonate solution was added to the reaction solution and stirred, followed by extraction with ethyl acetate. The organic phase was washed with a 5% aqueous sodium chloride solution and then dried over anhydrous sodium sulfate. The organic phase dried was concentrated under reduced pressure, and the resulting crude product was purified by a silica gel column chromatography (eluent: chloroform/methanol=50/1 to 30/1) to obtain N-(1-phenylcyclohexyl)-1H-indazole-5-carboxamide (62 mg, 78%).

Procedure:
To a suspension of 318 (10 g, 22.05 mmol) in EtOH (216 ml) and water (108 ml) was added iron powder (10.47 g, 187 mmol) and ammonium chloride (1.015 g, 18.97 mmol). The mixture was heated to reflux for 30 min, filtered while hot and the solids were washed with ether (200 mL). The filtrate and washings were combined and concentrated to afford title compound 319 (9.62 g, 99% yield) as a beige solid.
