الإجراء التجريبي

A solution of 2-fluoro-4-iodopyridine (prepared as described in Rocca, P. et al J. Org. Chem. 1993, 58, 7832-7838) (8.72 g, 39.1 mmol) in 80 mL of ethanol was treated with 20 mL of hydrazine hydrate and the mixture was stirred at room temperature (24-25° C.) for 20 hours. At the end of the reaction, the mixture was concentrated in vacuum and the resulting solid triturated with a mixture of hexanes/diethyl ether affording (8.52 g, 93%) the desired compound that was used in the following steps without further purification.
