Reaktionsschritte

Hydrazine (17.93 mg, 0.560 mmol) was added to methyl 5-chloronicotinate (80 mg, 0.466 mmol) in methanol (8 mL) and heated overnight at 70° C. The reaction was monitored by TLC. After completion of the reaction, the solvent was removed by vacuum and the compound was purified by column chromatography affording the title compound (40 mg). 1H NMR (400 MHz, CD3OD): δ 8.85 (d, 1H, J=2.0 Hz), 8.70 (d, 1H, J=2.4 Hz), 8.22 (t, 1H, J=2.0 Hz). ESI-MS: 172.0 [M+H]+.
