실험 절차

A 2:3 mixture of 5-(prop-1-en-2-yl)-1H-indazole and 1H-indazole (0.9 g), 10% Pd/C (0.2 g) in 150 mL of methanol was stirred at room temperature under H2 balloon for 3 hours. Pd/C was filtered off and the filtrate was concentrated under reduced pressure to give crude 5-isopropyl-1H-indazole (0.85 g) as an oil. LCMS: (M+H)+=161.
