Participants

Reaction Steps

A suspension of 2-(3-bromo-4-nitro-1H-indazol-1-yl)acetohydrazide (0.865 g) in anhydrous toluene (20 mL) was treated at ambient temperature with 1 equivalent of acetic anhydride. The reaction mixture was stirred at ambient temperature for 16 hours and concentrated under reduced pressure to afford the product (0.98 g) as an off-white solid.
