Reaction Steps

1.27 g (4.77 mmol) of 4-[3-(3-nitro-phenyl)-1H-pyrazol-4-yl]-pyridine was suspended in methanol (200 mL). Pd/C 10% (250 mg) was added and the mixture was agitated under hydrogen pressure (50 psi) in a Parr apparatus at room temperature for 4 hours. The catalyst was then filtered on a Celite pad and washed with methanol. The filtrate was concentrated to dryness to obtain 1.1 g (98% yield) of 3-(4-pyridin-4-yl-1H-pyrazol-3-yl)-phenylamine as an off-white solid.
