Reaction Steps
To a solution of 1-methyl-1H-pyrazol-3-amine (9.5 g, 98 mmol) and acetonylacetone (11.2 g, 98 mmol) in toluene 150 mL), AcOH (1.5 mL) is added, heated to reflux with a water separator until the formation of water ceased. Concentrated to dry. The residue is purified by flash column to give product. MS (ESI) m/z 176.3 (M+1).
