Reaction Steps
5-Cyclopropyl-1H-pyrazol-3-amine (5 g) was slurried in dioxane (80 mL) and N,N-dimethylformamide (80 mL), then phthalic anhydride (6 g) was added and the reaction was heated at 120° C. for 4 days. The reaction was cooled and concentrated. The crude material was triturated with isopropyl ether/ethanol 1/1 (30 mL) to provide the title compound.
