Reaction Steps

3-((3-amino-2-cyano-1-(methylthio)-3-oxoprop-1-en-1-yl)amino)benzoic acid was then suspended in 10 mL EtOH and hydrazine hydrate (124 μL, 1.0 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 4-((5-amino-4-carbamoyl-1H-pyrazol-3-yl)amino)benzoic acid as a yellow powder. Product was allowed to dry under vacuum for 1 hr.
