5-Fluoro-2-nitrobenzaldehyde Use and Manufacturing

5-Fluoro-2-nitrobenzaldehyde; Dissolve (5-fluoro-2-nitrophenyl)methoanol (13.92 g, 81.08 mmol) in dichloromethane (284 mL). Add 4Å molecular sieves (73 g) and pyridinium dichromate (36.58 g, 97.3 mmol). Stir the mixture at 20°C for 6 hours. Filter the crude reaction mixture through a short silica gel column. Remove the solvent under reduced pressure and purify the residue by flash chromatography (silica gel, 10-20percent ethyl acetate/hexane) to obtain 9.43 g (69percent) of title compound as colorless oil. 'H-NMR (CDCl3) : 8 10.44 (d, 1H), 8.22 (dd, 1H), 7. 62 (dd, 1H), 7.41 (ddd, 1H)
