実験手順

2-cyano-3-((4-(4-isopropylpiperazin-1-yl)phenyl)amino)-3-(methylthio)acrylamide was then suspended in 10 mL EtOH and hydrazine hydrate (1 eq.) was added dropwise. Reaction was heated at 75° C. until intermediate was absent (HPLC). Once intermediate was absent (18 hrs), reaction was brought to room temperature and filtered to obtain 5-amino-3-((4-(4-isopropylpiperazin-1-yl)phenyl)amino)-1H-pyrazole-4-carboxamide as a purple powder. Product was allowed to dry under vacuum for 1 hr.
