Participants

Reaction Steps

A solution of 4-methoxybenzoic acid N′-(4-amino-3-nitrobenzoyl)-hydrazide (750 mg, 2.27 mmol) and Burgess reagent (1.62 g, 6.81 mmol) in THF (15 mL) was microwaved at 150° C. for 20 min. The solvent was removed under reduced pressure and the residue was purified by flash chromatography (heptane/EtOAc=1:3) to give the title compound as a yellow solid. MS: m/z 313 (M+1).
