Participants

Reaction Steps

5-amino-3-(pyridin-3-ylamino)-1H-pyrazole-4-carbonitrile (100 mg) was then suspended in EtOH (4 mL) and 4-hydroxybenzaldehyde (31 mg, 1 eq.) and piperidine (1 drop) were added. Stirred at reflux until intermediate was absent (HPLC). After reaction was complete (18 hrs) it was brought to room temperature and filtered to obtain 5-((4-hydroxybenzylidene)amino)-3-(pyridin-3-ylamino)-1H-pyrazole-4-carbonitrile as a yellow powder. Powder was washed with EtOH. Product was allowed to dry under vacuum for 1 hr (40 mg, 53% yield).
