Reaction Steps

To a stirred suspension of potassium fluoride (457 mg, 7.8 mmol) in dry DMSO (20 ml) was added a solution of isovanillin (1.0 gm, 6.57 mmol) in dry DMSO (20 ml). The reaction contents were heated at 140° C. for 10 min. A solution of 4-fluoro-3-nitrobenzotrifluoride (1.37 gm, 6.57 mmol) in dry DMSO (10 ml) was added to the above suspension and the reaction mixture was stirred at 140° C. for 4.0 h. The reaction mixture was cooled to room temperature and the contents were poured into water (200 ml) and extracted with ethyl acetate (100 ml×3). The organic extracts were combined and washed with 1N sodium hydroxide (50 ml×2), water and brine and dried over anhydrous sodium sulfate. The organic layer was concentrated in vacuo to obtain 3-(2-nitro-4-trifluoromethyl phenoxy)-4-methoxy benzaldehyde as a pale yellow solid (2.0 gm).
