2-(3-fluorophenoxy)acetaldehyde

Conditions: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2.00 g (17.8 mmol) of m-fluorophenol was dissolved in 50 ml of dimethylformamide, 785 mg (19.6 mmol, 60% by weight, mineral) of sodium hydride and 3.21 ml (21.3 mmol) of bromoacetaldehydediethylacetal were successively added thereto, and the mixture was heated to 60° C. After completion of the reaction, brine was added thereto and the mixture was extractedwith ethyl acetate. Theorganiclayerwaswashedwith brine, dried over magnesium sulfate and then evaporated, to give a crude product. The crude product was subjected to 105 g of Cromatorex NH silica gel (ethyl acetate:hexane=1:40), to give 3.17 g (13.9 mmol, 78.1%) of the title compound as a yellow oil. was added Theorganiclayerwaswashedwith brine, dried over magnesium sulfate evaporated to give a crude product
