実験手順

5-amino-3-((4-isopropylphenyl)amino)-1H-pyrazole-4-carboxamide (850 mg) was suspended in 15 mL of ethanol and 4-hydroxybenzaldehyde (601 mg, 1.5 eq.) and piperidine (0.50 eq, 168 μL) was added. Stirred the reaction at reflux until starting material was absent and confirmed by HPLC. After reaction was complete (18 hrs) it was brought to room temperature and filtered to obtain 5-((4-hydroxybenzylidene)amino)-3-((4-isopropylphenyl)amino)-1H-pyrazole-4-carboxamide as a yellow to orange powder. The product was washed with ethanol to remove any excess 4-hydroxybenzaldehyde. Product was allowed to dry under vacuum for 1 hr (1.15 g, 97% yield).
