実験手順
Hydrazine hydrate (12.50 mL, 256 mmol) was added dropwise to a solution of 2-fluoro-3-iodopyridine (preparation 26a, 5.72 g, 25.7 mmol) in ethanol (43 mL) and the resulting mixture was stirred at room temperature for 24 hours and then at 35° C. for a further 24 hours. The solvent was then evaporated in vacuo and water was added. The white solid that formed was filtered, washed with water and dried to yield the title compound (2.78 g, 46%) as a white solid which was used without further purification.
