Reaction Steps

Dissolved 5-amino-3-((3-chlorophenyl)amino)-1H-pyrazole-4-carbonitrile (58 mg) in 4 mL ethanol and added 0.250 mmol of 4-fluoro-2-methylbenzaldehyde followed by a single drop of piperidine. This solution was then heated to 85° C. for 17 hrs, then the ethanol was evaporated and the resulting product was scraped from the reaction vessels. The powder was then resuspended in 4 mL of MeOH and 3 eq. of sodium borohydride was added and left stirring overnight at room temperature. Then MeOH was then evaporated and the product C29 was scraped and collected. (50 mg)
