Reaction Steps

5-amino-3-((3-chlorophenyl)amino)-1H-pyrazole-4-carbonitrile (100 mg) was then suspended in EtOH (4 mL) and 4-[{5-(Trifluoromethyl)pyridin-2-yl}oxy]benzaldehyde (230 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 3-((3-chlorophenyl)amino)-5-((4-((5-(trifluoromethyl)pyridin-2-yl)oxy)benzylidene)amino)-1H-pyrazole-4-carbonitrile as a yellow powder. Powder was washed with EtOH. Product was allowed to dry under vacuum for 1 hr (217 mg, 52% yield).
