Reaction Steps

3-hydrazinylbenzoic acid (1.52 g, 10 mmol)), 2-fluoro-5-iodobenzaldehyde (2.5 g, 10 mmol) and caesium carbonate (3.26 g, 10 mmol) were stirred in DMF (10 mL) at r.t. under argon atmosphere for 2.5 h. Water (40 mL) was added and the clear solution was acidified with aqueous HCl (1.7 M). The beige-orange precipitate that formed was collected by, filtration, washed with water and dried in vacuo to give the title compound (3.75 g, 98%).
