Reaction Steps

5-amino-3-((3-chlorophenyl)amino)-1H-pyrazole-4-carboxamide was then suspended in EtOH and 4-methylsulphonyl benzaldehyde (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 product as a yellow powder. Powder was washed with EtOH. Product was allowed to dry under vacuum for 1 hr.
