Participants

Reaction Steps

Phthalic anhydride (827 mg, 8.26 mmol) was added to a solution of 5-aminoindazole (1.0 g, 7.51 mmol) in acetone (60 ml) at room temperature, and the resulting mixture was refluxed for 4 hours. The solid precipitated was collected by filtration and dried under reduced pressure to obtain 4-(1H-indazol-5-ylamino)-4-oxobutanoic acid (1.79 g, 100%).
