Versuchsvorschrift

The title compound was prepared by heating a mixture of 2,5-bis(2,2,2-trifluoroethoxy)acetophenone (200 mg, 0.633 mmol), p-tolualdehyde (75 ul, 0.633 mmol), methanol (5 ml) and NaOH (200 ul, 10M) for 24 h. The mixture was cooled to room temperature, diluted with ethyl acetate (100 ml), wash with water and saturated aqueous NaCl, dried over anhydrous sodium sulfate and then concentrated in vacuo. The residue was purified by column chromatography using hexane:ethyl acetate (4:1) to give a yellow solid (32 mg, 12.2%). 1H NMR (CDCl3): 7.67 (d, J=15.6 Hz, 1H), 7.50 (d, J=8.4 Hz, 2H), 7.40 (d, J=15.6 Hz, 1H), 7.28 (d, J=3.3 Hz, 1H), 7.22 (d, J=8.1 Hz, 2H), 7.12 (dd, J=3.3, 9.3 Hz, 1H), 6.96 (d, J=8.7 Hz, 1H), 4.44-4.33 (m, 4H), 2.39 (s, 3H).
