Reaction Steps

Methyl 5-bromo-6-chloronicotinate (100 mg, 0.399 mmol) was added to hydrazine (19.19 mg, 0.599 mmol) in methanol (8 mL) and heated overnight at 70° C. The reaction was monitored by TLC. Upon completion of the reaction, the solvent was removed by vacuum, and the compound was purified by column chromatography affording the title compound (20 mg). 1H NMR (400 MHz, CD3OD): δ 8.33 (d, 1H, J=2.4 Hz), 8.01 (d, 1H, J=2.4 Hz).
