Reaction Steps
Methyl 3-bromo-4-chlorobenzoate (120 mg, 0.481 mmol) was added to hydrazine (23.12 mg, 0.721 mmol) in methanol (8 mL) and refluxed for 12 h at 70° C. Reaction was monitored by TLC. After completion of the reaction, the solvent was removed by vacuum and then compound was purified by column chromatography affording the title compound (30 mg). 1H NMR (400 MHz, CDCl3): δ 8.02 (d, 1H, J=1.6 Hz), 7.60 (dd, 1H, J=2.0 & 8.0 Hz), 7.52 (d, 1H, J=8.0 Hz), ESI-MS: 250.9 [M+H]+.
