Reaction Steps

5-amino-3-((3-chlorophenyl)amino)-1H-pyrazole-4-carbonitrile (100 mg) was then suspended in EtOH (4 mL) and 6-fluoro-4H-1,3-benzodioxine-8-carbaldehyde (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 A29 as a yellow powder. Powder was washed with EtOH. Product was allowed to dry under vacuum for 1 hr (103 mg, 60% yield).
