Participants

Reaction Steps

Ethyl 2-[1-(4-nitrobenzyl)-1H-indazol-3-yl]acetate (225 mg, 0.663 mmol) was dissolved in methanol (20 mL). 10% Pd/C(18 mg) was added, and reacted under hydrogen atmosphere for half an hour. TLC (petroleum ether:ethyl acetate=2:1) indicated that starting material disappeared. It was filtered to remove solid, rotate evaporated to dryness to remove the solvent, and the resulting solid was used for the next step directly.
