Reaction Steps
Under argon, 750 mg of N-[2-(3-hydroxy-7-methoxy-1H-indazol-4-yl]trifluoroacetamide is heated to 120° C. with 5 ml of aqueous hydrogen bromide (65%) for 2 hours. The crystallized product is recrystallized from methanol/diethyl ether, yielding 680 mg of 2-(3,7-dihydroxy-1H-indazol-4-yl)ethylamine, hydrobromide, decomposition point 270°-273° C.
