2-Chloro-5-nitrobenzaldehyde → 2-Fluoro-5-nitrobenzaldehyde

Participants

Reaction Steps

18.6 g (0.1 mol) of 2-chloro-5-nitrobenzaldehyde and 11.6 g (0.2 mol) of dry potassium fluoride in 50 ml of dimethylformamide are stirred for 12 hours at 100° C. The solvent is then distilled off in vacuo and the residue is stirred in 100 ml of water. The crude 2-fluoro-5-nitrobenzaldehyde is filtered off under suction, washed with water and dried. 16.7 g of 2-fluoro-5-nitrobenzaldehyde with a content of 96% are obtained.
